Computational Fluid Dynamics (CFD) is pretty serious business. Every day it’s used in a wide range of industries around the world to optimize products for some very practical purposes. Cars? Check! Planes? Check. Medical devices, consumer electronics and power generation? Check, check and check. But sometimes you come across things that make you giggle. And since it’s a grey and gloomy day in England I thought you may like to join me for a giggle too. So let’s go to a special zoo.
A CFD zoo! And yes I know what you’re thinking… this is a rather bizarre zoo but hey don’t rain on my parade … we get enough of rain here as is :-):
A quick Google search turns up a few research projects involving dolphins out there. In 2006, I came across one by the Crimean State Medical University. The group was interested in investigating the mystery of dolphins’ speed. Research scientist V.V. Pavlov used COSMOSFloWorks™ to simulate the detailed hydrodynamics of the flow around the dorsal fin of the harbor porpoise (read the paper here). He found that the shape of the dolphin’s skin matches the flow conditions around the dorsal fin. Apparently, by complying with flow conditions, the skin has the effect of suppressing instability growth in the boundary layer and reducing turbulence. What is really neat about this research is that this information could possibly aid in the design of compliant walls which might increase speed and reduce fuel consumption of ships and airplanes at some point. Cool!
This is a gem from a long time ago too. The development team was testing complex geometries that can be meshed and analyzed with FloEFD. While the analysis had no real application whatsoever it was a bit of good fun and it had me in stitches for days. All you had to say was “Moo!” to me at work and I’d have tears running down my face. Who says you can’t bring fits of laughter to your colleagues with the help of CFD?
Not to be outdone by the general purpose CFD team, the electronics cooling development team decided to test the limits of geometric complexity with our FloTHERM XT product line last year. This “cool” fish here is the result! The plot made me giggle not because it’s absurd but because it made me think whether any of our customers were likely to design anything in electronics with a shape as complex as this. Hey… how about a fish-shaped heatsink or enclosure with liquid cooling? No? Oh well, never mind …
One of my favorite holidays, Thanksgiving, is only weeks away. It’s always been a time of celebration for me and my family. A few years ago my parents absolved themselves of throwing a huge family get together and passed the party baton to the next generation. The girls now split the burden among us. My niece gets the desserts (glutton-free and sugar-free … this is Los Angeles after all). One sister does the fixin’s (AKA stuffing and veggies) while the other does the fish (there’s always someone who doesn’t like turkey). I make my specialty… yams. And before you question the division of labor, let me just say that I make it from scratch and have to make mass quantities of the stuff as people tend to eat seconds and thirds. It’s always the first leftover to run out.
The star of the show, the turkey, is always cooked by my mom though. Why? Because the next generation has not quite mastered the art of cooking a massive turkey that doesn’t turn into turkey jerky. I used to think that we are all really bad cooks until I read one of my colleague’s blogs last year. He used FloEFD to model and analyze cooking a turkey. I used my newly found knowledge last year for Boxing Day and presto lovely turkey! To read the blog and learn how to cook a succulent turkey this year, please follow this link But you know what? I’m not going to tell my mom that I’ve discovered her secret. After all, who’d make the yams? And we all know, Thanksgiving dinner without yams is like Christmas without presents
And so ends our day at the CFD zoo … with a bit of a giggle and a wee bit peckish (all this talk of Thanksgiving dinner has made me hungry). If you have any interesting or odd things that you’ve analyzed with our software solutions and would like to share them with us then please send them to me at firstname.lastname@example.org by end of October 2014 and I’ll do a special post. And please include a description … I think we’d all love to hear the background stories (bad jokes are optional). I’ll be happy to attribute them to you but if you want to remain anonymous that’s ok too. Just let me know what you prefer and I’ll take it from there. I really hope you take me up on this offer. I can’t wait to see what kind of fun y’all have had with CFD.
Until next time,
PS. We are hiring a new Product Marketing Manager. It’s a really cool job and the group is managed by a great guy so if you’re interested then please ping me. Here’s the job description (and good luck!).
