Now I’m not a CFD expert and have never run the CFDesign product before but I didn’t have much trouble ramping up. I happened to have a hybrid rocket nozzle with the design in Solid Edge that I used today (note that the video in the last link is unrelated to this nozzle but shows why nozzle design is important) . nozzle in the rocket assembly

So, with a little help from the CFDesign 2010 software, I was able to map the flow patterns...

...and also get an interesting look into the particle velocity as it flows through the nozzle.

Now I don’t build many rockets - this is actually my son’s hybrid rocket that he is working on while at the university. However, I do build custom PC’s as a hobby and CFDesign has quite a few tutorials just for things like this. I wonder if I can get a good design set up for optimal cooling of an over clocked CPU before my license runs out.
