Hi Would you please tell me which turbulent model (in the viscous panel of fluent program) should I choose for highly internal compressible flow, for example for a gas flow through a pipe under high pressure gradient?

Well actually i'm modelling the flow of very high pressure gas in a tube which it the mach number shouldn't be above 1. The gas is stagnant in a vessel and then accelerate through the pipe to the atmosphere. The pressure ratio is almost 300 with no combustion. Thanks a lot

Hi Then you use K-epsilon Model Its suiteble for your problem. Mesh generation is important in Wall treatment. Good luck
