## Main Question or Discussion Point

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.
