How to do simulations for pressible flow

October 5, 2003, 13:07

Hello, I am a novice to CFD and fluent.I wanted to do some flow simulations in a pipe with inviscid and compressible flow options. Can any one tell me how to do the same. I tried to find out in Fluent manual and tutorial. But its not mentioned clearly about how to solve the problem for copressible flow.

Can you please tell me how to set up the boundary condition for the same geometry(say a converging nozzle) for Inviscid flow and compressible flow through it.

Thnaks and regards for help in advance... gaurav

I mean COMPRESSIBLE FLOW

Well its easy in Fluent: 1. just keep the Courant # low ...say less than 1 initially

2. Use pressure inlet n pressure outlet as BCs..

what else....any specific problem????
