Tiny Bubbles was a hit song by Don Ho (before even my time). Tiny Density Gradients just won’t make the charts.

But that’s what happens when you take a pure fluid substance to high enough pressure or temperature: the distinction between...

You will of course remember this blog post from almost three years ago, “Why Stratified Tanks Stir Me Up.” I mean, who wouldn’t remember a complaint-ridden,...

First, let’s be clear: I’m not addressing political dysfunction. If that was your first reaction upon seeing this title, then compromising itself has come to have a negative connotation.

I know it sounds better in engineering to call a...

It began with a simple question: How difficult is it to make the <redacted name of a famous fictional armored vehicle made a long time ago in a studio far far away> walk correctly with...

Thanks to fun headlines like “Geysers erupt because they’re all bendy inside,” this paper caught my...

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...

Reacting Flows

Tuesday May 5th, 2pm MT (1pm PT, 4pm ET)

Reacting Flows is a capability that allows FloCAD to simulate fuel reformers, deal with the electrochemistry of flow batteries, predict combustion reactions in gas generations, and work with ionized and dissociated gases.

This webinar will explain how to use a working fluid as a reactant. It will also detail various options for determining reaction rates such as equilibrium, finite rate with stoichiometric coefficients, and percent complete based on inflowing reagents. Example applications are summarized.

Dissolved Gases

Thursday May 7th, 2pm MT (1pm PT, 4pm ET)

When vapor meets liquid, it can condense. When gas (NCG) meets liquid, it can dissolve. When there is too much gas in the liquid, it can either evolve slowly at a wall or at the surface ... or it can come out explosively.

Whether your interests are environmental control, liquid propulsion, fire retardant delivery, or beer, this webinar offers a rare glimpse into an advanced modeling topic.
