CFD Simulations

[robbrown]

Can someone provide me to a guide, book or some kind of tutorial that would help me in learning how to simulate the flow of gases in a rocket nozzle?

I am trying to investigate the effect of my expansion ratios, nozzle geometry and other design parameters and simulate it.

I would be very grateful for any kind of help, I am using my school's computers and I can get access to both Comsol 4.0 and Ansys 13.

Both products should provide tutorials and manuals for using their code. They will also probably have a test of verification and validation problems.

Yes, but are there more detailed tutorials?
I like the ones they provide, but I would like to check more out. I have already made a few simulations regarding rocket aerodynamics but I still can't get a clear handle on how to work with time-dependent simulations and such. I would really appreciate any material that would help me, preferably Comsol.
