CFD, Giving Our Prototype Machinists a Break
Computational fluid dynamics, of CFD, was a central focus of recent industry events, and I find the topic keeps cropping up in mil/aero discussions of late. In fact, CFD simulation tools are increasingly being employed by military prime contractors (aka, primes) to meet contract requirements, such as survivability in extreme environments and temperatures, … Read More

I really enjoyed both of the Web Seminars on heat sinks; Heatsink 101 presented by Alexandra Francois-Saint-Cyr and Heatsink 201 presented by Dr. John Parry. I was especially interested in a couple of equations presented in Heatsink 101 that estimated h (convective heat transfer coefficient) and minimum fin spacing. The equations were derived from a Flat Plate in Parallel Flow theory but were simplified … Read More

We are all familiar with the industrial revolution – a period where major changes in the way we did stuff (whether it was food production, manufacturing, moving from point A to point B … pretty much everything we did) impacted not only the economy but also our culture as well. So imagine my surprise when I heard on the radio that we are smack-dab in the middle of the next industrial revolution.
Gain … Read More

When budgets are tight most managers think about the same thing before they sign on the dotted line: is this new tool going to help us get more done faster/better/smarter? If the answer is no then like most managers I don’t make the investment. Instead I focus on an activity that’s going to give me the best return on investment (ROI).
That’s why last week I talked about time compression being … Read More

I’m rather proud of our products so whenever I speak with people I have a tendency to talk about features and functions… the juicy stuff. So it’s easy to forget that one of the main benefits of simulation is time compression.
In the not too distant past, most companies used to do analysis only after the physical prototyping phase. The design team would create a cool design, the proposed design would … Read More

From time to time I lurk around CFD related forums – just to see what people are talking about. A couple of weeks ago I found a posting on the subtleties of meshing and its relation to accuracy. The discussion rapidly became quite heated – there were some folks who believed that unless simulation gives you 100% accuracy then it is useless while others didn’t believe that accuracy is the only factor … Read More

So before I was talking about bike racing and whether teams used CFD. So do they? Could they? What exactly could they do with CFD?
Well I’m thinking that if you had a model of bike and rider you could vary the angle of lean on the bike for a start and see the resultant forces to give you an idea of stability. Remember that stability is important for rider confidence. It’s pretty hard to pull this kind … Read More
