This is the third post of a three-part blog on two-phase heat transport devices. It was supposed to be the final part, but if I get an inkling (and don’t retire first) perhaps I will continue with oscillating pipes or vapor chambers. If I do retire, it has been nice getting to know all of you...

To say that Pythagoras, who lived over 2500 years ago, would be astounded by what I just did in his honor says nothing. I mean, let’s face it: he’d be astounded by kale chips, boomerangs, and tubas.

So I didn’t do it for him. I didn’t do it for...

More than once, I got into an argument with a boss in the 80s. And I almost never had a boss who was a thermal engineer during that decade. They never knew what to do with us thermal people. Systems? Power? Materials? Propulsion? Avionics? Been...

I don’t mean “blood and guts” metaphorically. But I don’t mean it literally either. Best to call it analytic “blood and guts.” Plus, we’ll skip the guts for now, so you can relax.

And as you’ll see, I could have called this post “City...

Heat Pipes: aka Magic Pipes

Jane Baumann

In my previous blog on thermosiphons, I introduced a multipart blog on two-phase heat transport devices. With this blog, I would like to introduce you to heat pipes (sometimes written...

I pulled into the parking lot of a small print shop in an industrial-looking area in Dublin, Ireland. I looked back at the one lane bridge I had just crossed. It was an ordinary looking bridge spanning a small canal and a rail line. I walked to the bridge,...

It might be apparent by now that I get bothered by silly or strange things. But what’s the point of even having a pet peeve if you can’t enjoy it?

Thermally stratified tanks bother me.  Fill a tank partially full of cryogenic liquid, leave it...

My husband and I have been lucky to have two wonderful human children, one who is a mechanical engineer living and working in California and the other is in her last year of college (opting not to be an engineer). My husband is Jim Harris, a mechanism...

If, like me, you are a fan of the sitcom The Big Bang Theory, you may have heard the Spherical Chicken joke in the episode “The Cooper-Hofstadter Polarization:”

There's this farmer, and he has these chickens, but...

The field of positive psychology is devoted to making so-called “normal people” happier. A key observation is that people tend to be happiest when they are in a state called...

dispersed vs. coalesced front

Tuesday, June 26, 2018, 1-2pm PT, 4-5pm ET

This webinar describes flat-front modeling, including where it is useful and how it works. A flat-front assumption is a specialized two-phase flow method that is particularly useful in the priming (filling or re-filling with liquid) of gas-filled or evacuated lines. It also finds use in simulating the gas purging of liquid-filled lines, and in modeling vertical large-diameter piping.

Prerequisites: It is helpful to have a background in two-phase flow, and to have some previous experience with FloCAD Pipes.
