Hello everyone,

I solved the flow inside a convergent divergent nozzle. I used the pressure inlet and pressure outlet boundary coditions. In the supersonic outlet flow the solution converged with solution close to the 1-D analytical solution. I tried to capture the shock wave in the divergeny portion, I increased the pressure at the outlet boundary but unforunately, the flow is always supersonic at the exit and there is no shock wave.

Can anyone help be in this issue. Thanx in Advance.

Jim

Hi! Try the following: 1. Create additional space out of nozzle 2. Use the unsteady solver 3. Set pressure on outlet bondary at once
