What if your heat pipe wall is too complex to represent with the FD surfaces and solids native to a FloCAD HeatPipe, and FE meshes must be used?

What if your heat pipe cross section changes along its length, yet FloCAD HeatPipes can't be joined end to end as can a regular Pipe?

The sample problem takes on a complex extruded evaporator cross section that is joined to a condenser section that has been machined down to a circular cross section. It demonstrates how to:

  • Represent the complex evaporator extrusion as an FE mesh while using a massless shell as the heatpipe for the rest of its length (Example 1)
  • Represent some or all of the extrusion as an effective cross section (Example 2), continuing that effective cross section along the entire length of the heatpipe
  • Use a Thermal Desktop (TD) Conductor instead of a FloCAD HeatPipe to avoid the above limitations for certain common situations (Example 3)

Some discussion of the Vapor Core Diameter meaning and alteration is also included.
