Validation of axisymmetric Euler solver
 
I'm working in a program solver for the compressible Euler equations based in finite volume discretization and a sequential solution algorithm (PRIME compressible). I want to solve internal flows in axisymmetric domains so I need to validate my program with test cases that have this caracteristics. I'm wondering if someone could help me to find this test cases.

(1). The nozzle flow would be ideal in this case. (2). Converging and diverging nozzle has been used in various method and code development. I don't have any particular reference, but I think you should look in AIAA journal from 60's through early 80's. (3). Or you can do the search in the nozzle flow area.

Just to get things off the ground, a simple Laval nozzle will do fine. You can check Mach numbers, pressures, etc. against area ratio.

If you are interested in more detailed physics like shock capturing or something else then post what those details are.

Re: Validation of axisymmetric Euler solver
 
a similar question was asked a few days ago (ie test cases to validate euler codes) my answer was to use test cases with exact analytical solutions. you can search the forum under my name to find the message
