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...

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

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,...

Introduction to Two-phase Flow

September 24, 2-3pm MDT

This webinar introduces basic concepts in two-phase flow modeling including quality, void fraction, flow regimes, slip flow, pressure drops and accelerations, and heat transfer.

No knowledge of CRTech software is required. However, references to the corresponding FloCAD features will be made to assist users of that product.

Introductory FloCAD Training

Class times: September 5, 10, and 12, 2019, 9:00 am to 12:00 pm MDT daily
Cost: no charge (attendees must have an active support contract)

CRTech will be hosting introductory training for FloCAD (Flow Modeling in Thermal Desktop). This is our standard FloCAD class previously hosted in a classroom environment and now restructured for an online teaching environment.

The class will introduce single-phase fluid modeling concepts and how to build fluid models within the FloCAD work environment. Topics covered include an introduction to fluid modeling components, geometric versus non-geometric modeling options, working with FloCAD Pipes, solution control, and an introduction to path and pipe libraries.

The class will be broken into three two- to three-hour sessions held over a 3 day period. The format will be online lecture and demonstration with opportunities to ask questions. Hands-on lab work will be provided to students to work on after each session. To gain the most from this class, students are encouraged to attend all three sessions.

Prerequisites: Attendees must have basic working knowledge of Thermal Desktop as many of its base features will not be covered in this class but their usage is required for FloCAD.

Eligibility Requirement: This class is a service to our customers. All attendees must have an active support contract. If you are unsure of your support status, please contact CRTech.
