Simulation of Normal Shock in Ansys

10ume039 · February 1, 2016, 04:27

I have to simulate a Normal shock in a converging- diverging nozzle. I have fixed geometry nozzle. I have taken the pressure inlet and pressure outlet boundary conditions.
Assuming no shock I have found the outlet pressure based on geometry I have. After that, I start increasing the outlet pressure to get a normal shock in the diverging section but there is no effect on the flow.
Can anyone suggest me why so happen and how can I sort it out?

Thanks in Advanced........
