Laval nozzle(convergent divergent) code
 

does any one know where I can find how to write a code for simulating a laval nozzle?
the input pressure of nozzle is 300 bar(connected to a vessel) and output (connected to another vessel) increases from atmospheric pressure to equilibrium with first vessle.
both vessels are at room temprature

Hi
 

Do you want to simulate the 3D nozzle or a quasi 1D model. if Quasi 1D model is sufficient you can refer to Compuataional Gas Dynamics book by Culbert Lanney, this is an excellent book to start for Gas dynamics problems.

can anyone help me in designing supersonic 3d nozzle.. i also need coding for nozzle design. pls send me in dinesh_astronaut@yahoo.co.in
