Some example code snippets are also provided to aid potential users in the development of their own utilities. Following the overview are descriptions and algorithm methodologies of the new capabilities added to the GSFC framework, including: a new PI heater/controller approach for improved steady state predictions, selective copying of symbol over-rides from one source CaseSet to destination CaseSet(s), comparison of submodel object counts between a source and destination model to verify model integration, comparison of thermo-optical and thermo-physical properties between models, and improved display of extracted thermo-optical and thermo-physical properties for documentation.</p> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field--text-with-summary.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-upload-files--publication-files.html.twig * field--node--field-upload-files.html.twig * field--node--publication-files.html.twig * field--field-upload-files.html.twig * field--file.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-upload-files field--type-file field--label-inline clearfix"> <div class="field__label">Upload Files</div> <div class="field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'file_link' --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> <span class="file file--mime-application-pdf file--application-pdf"> <a href="/sites/default/files/2022-09/ICES-2022-396.pdf" type="application/pdf">ICES-2022-396.pdf</a></span> <!-- END OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> </div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-source--publication-files.html.twig * field--node--field-source.html.twig * field--node--publication-files.html.twig * field--field-source.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-source field--type-string field--label-inline clearfix"> <div class="field__label">Source</div> <div class="field__item">ICES</div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-author--publication-files.html.twig * field--node--field-author.html.twig * field--node--publication-files.html.twig * field--field-author.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-author field--type-string field--label-inline clearfix"> <div class="field__label">Author</div> <div class="field__item">Hume L.

This file allows applications to be developed in the .NET framework and interface to a number of object types within a Thermal Desktop model. The release of 6.1 expands the subset of objects able to be manipulated and now includes the raw geometrical information of surfaces. With the release of 6.1, the API was now referred to as OpenTD. This paper discusses some of the utilities and capabilities developed using the OpenTD API at the NASA Goddard Space Flight Center. These include utilities to help with configuration control of models and case sets, addition of logic to better process heater performance, and a methodology implemented to allow for submodel level processing of radiation couplings to include smaller radks where needed in a cryogenic region without using the same criteria for the warmer portions of the model. This last utility is targeting a reduction in run time without sacrificing accuracy. Lastly, some lessons learned, work-arounds, and wishes for the next release of the OpenTD API are also presented.</p> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field--text-with-summary.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-upload-files--publication-files.html.twig * field--node--field-upload-files.html.twig * field--node--publication-files.html.twig * field--field-upload-files.html.twig * field--file.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-upload-files field--type-file field--label-inline clearfix"> <div class="field__label">Upload Files</div> <div class="field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'file_link' --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> <span class="file file--mime-application-pdf file--application-pdf"> <a href="/sites/default/files/2022-09/ICES-2020-297.pdf" type="application/pdf">ICES-2020-297.pdf</a></span> <!-- END OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> </div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-source--publication-files.html.twig * field--node--field-source.html.twig * field--node--publication-files.html.twig * field--field-source.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-source field--type-string field--label-inline clearfix"> <div class="field__label">Source</div> <div class="field__item">ICES</div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-author--publication-files.html.twig * field--node--field-author.html.twig * field--node--publication-files.html.twig * field--field-author.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-author field--type-string field--label-inline clearfix"> <div class="field__label">Author</div> <div class="field__item">Hume L.

Thermoelectric coolers, being solid state devices, have no moving parts which makes them inherently reliable and ideal for cooling components in a system sensitive to mechanical vibration. The ability to use TECs to heat as well as cool makes them suitable for applications requiring temperature stabilization of a device over a specified temperature range. Although these devices have been around for years, they are gaining popularity in the aerospace industry for providing temperature control within optical systems and for loop heat pipes.</p> <p>Historically, modeling and sizing of thermoelectric coolers was left to the analyst to work off-line from the modeling task. The analyst would then need to create his own logic in SINDA for simulating the cooler. This presenation will demonstrate how thermoelectric coolers are now easily modeled using off-the-shelf simulation routines and 3D user interfaces. The analytical demonstration includes sizing of a cooler for a specific application based on area, temperature requirements and heat load through a series of parametric analyses. Cooler performance will also be characterized at the device and system level.</p> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field--text-with-summary.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-upload-files--publication-files.html.twig * field--node--field-upload-files.html.twig * field--node--publication-files.html.twig * field--field-upload-files.html.twig * field--file.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-upload-files field--type-file field--label-inline clearfix"> <div class="field__label">Upload Files</div> <div class="field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'file_link' --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> <span class="file file--mime-application-vnd-ms-powerpoint file--x-office-presentation"> <a href="/sites/default/files/publications/ModelingAndSizingTECs_0.pps" type="application/vnd.ms-powerpoint">ModelingAndSizingTECs.pps</a></span> <!-- END OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> </div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-source--publication-files.html.twig * field--node--field-source.html.twig * field--node--publication-files.html.twig * field--field-source.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-source field--type-string field--label-inline clearfix"> <div class="field__label">Source</div> <div class="field__item">Aerospace Thermal Control Workshop</div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-author--publication-files.html.twig * field--node--field-author.html.twig * field--node--publication-files.html.twig * field--field-author.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-author field--type-string field--label-inline clearfix"> <div class="field__label">Author</div> <div class="field__item">Jane Baumann</div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> Wed, 15 Jul 2015 20:33:31 +0000 bfc-admin 1208 at https://www.crtech.com WPI Nanosat-3 Final Report, PANSAT -

Nonetheless, if appropriate values of these unknown parameters are available for any specific electronics package, then its temperature response can be accurately predicted using modern thermal/fluid analysis tools.</p> <p>Traditionally, uncertainties are dealt with by a combination of testing, safety factors or margins, and worst-case design scenarios. Analyses are performed iteratively in a repetitive “point design evaluation” mode. Computer-based design simulation tools have emphasized increasing detail and fidelity to physical phenomena, seemingly ignoring the fact that the inputs to these simulations are highly uncertain.</p> <p>This paper describes both current and future methods of dealing with uncertainties in thermal engineering. It introduces advanced tools and alternative methodologies that can automate not only the quantification of reliability, but can also help synthesize designs on the basis of reliability. It advocates using rapid gains in computer speed not to increase the degree of detail in a model, but to help the engineer find a robust design by automating high-level design tasks.</p> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field--text-with-summary.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-upload-files--publication-files.html.twig * field--node--field-upload-files.html.twig * field--node--publication-files.html.twig * field--field-upload-files.html.twig * field--file.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-upload-files field--type-file field--label-inline clearfix"> <div class="field__label">Upload Files</div> <div class="field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'file_link' --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> <span class="file file--mime-application-pdf file--application-pdf"> <a href="/sites/default/files/publications/IPACK2001-15516.pdf" type="application/pdf">IPACK2001-15516.pdf</a></span> <!-- END OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> </div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-source--publication-files.html.twig * field--node--field-source.html.twig * field--node--publication-files.html.twig * field--field-source.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-source field--type-string field--label-inline clearfix"> <div class="field__label">Source</div> <div class="field__item">InterPack</div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-author--publication-files.html.twig * field--node--field-author.html.twig * field--node--publication-files.html.twig * field--field-author.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-author field--type-string field--label-inline clearfix"> <div class="field__label">Author</div> <div class="field__item">Brent A.

Improvements in both interprocess communications technology and numerical solutions have gone a long way towards meeting those demands.</p> <p>This paper describes a small slice of a larger on-going effort to satisfy current and future demands for integrated multidisciplinary tools that can be highly customized by end-users or by third parties. Specifically, the ability to integrate fully featured thermal/fluid simulations into Microsoft’s Excel™ and other software is detailed. Users are now able not only to prepare custom user interfaces, they can use these codes as portals that allow integration activities at a larger scale. Previous enabling technologies are first described, then examples and repercussions of current capabilities are presented, and finally in-progress and future technologies are listed.</p> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field--text-with-summary.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-upload-files--publication-files.html.twig * field--node--field-upload-files.html.twig * field--node--publication-files.html.twig * field--field-upload-files.html.twig * field--file.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-upload-files field--type-file field--label-inline clearfix"> <div class="field__label">Upload Files</div> <div class="field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'file_link' --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> <span class="file file--mime-application-pdf file--application-pdf"> <a href="/sites/default/files/publications/COMAPI-ICES.pdf" type="application/pdf">COMAPI-ICES.pdf</a></span> <!-- END OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> </div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-source--publication-files.html.twig * field--node--field-source.html.twig * field--node--publication-files.html.twig * field--field-source.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-source field--type-string field--label-inline clearfix"> <div class="field__label">Source</div> <div class="field__item">ICES</div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-author--publication-files.html.twig * field--node--field-author.html.twig * field--node--publication-files.html.twig * field--field-author.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-author field--type-string field--label-inline clearfix"> <div class="field__label">Author</div> <div class="field__item">B.

The software is able to simulate transient operation of vapor compression cycles, predicting pressures, coefficients of performance, and condenser/evaporator liquid positions in a closed two-phase system with a fixed fluid charge. The program can also be used to size components, to estimate the impact of tolerances and other variations, and to help estimate uncertainties given limited test data.</p> <p>SINDA/FLUINT has a user base numbering in the thousands. It has several graphical user interfaces, preprocessors, and postprocessors; has strong links to CAD and structural tools; and has built-in optimization, data correlation, parametric analysis, reliability estimation, and robust design tools.</p> <p>Nonetheless, widespread application to vapor compression cycles is comparatively recent (Ref 2), and is largely due to an increased demand for transient modeling of air conditioning systems. Toward this requirement, SINDA/FLUINT’s unique abilities to analyze transient two-phase phenomena have been recognized as being critical to achieving accurate performance predictions.</p> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field--text-with-summary.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-upload-files--publication-files.html.twig * field--node--field-upload-files.html.twig * field--node--publication-files.html.twig * field--field-upload-files.html.twig * field--file.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-upload-files field--type-file field--label-inline clearfix"> <div class="field__label">Upload Files</div> <div class="field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'file_link' --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> <span class="file file--mime-application-pdf file--application-pdf"> <a href="/sites/default/files/publications/vc.pdf" type="application/pdf">vc.pdf</a></span> <!-- END OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> </div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-source--publication-files.html.twig * field--node--field-source.html.twig * field--node--publication-files.html.twig * field--field-source.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-source field--type-string field--label-inline clearfix"> <div class="field__label">Source</div> <div class="field__item">ICES</div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-author--publication-files.html.twig * field--node--field-author.html.twig * field--node--publication-files.html.twig * field--field-author.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-author field--type-string field--label-inline clearfix"> <div class="field__label">Author</div> <div class="field__item">Brent A.
