Hi everyone,

I have simulate a laval nozzle with rhoSimpleFoam in OpenFOAM.
But I do not konw if there are shcok wave in my nozzle or not? Does anyone know, if it possible to visualise the shock wave in post-precoessing?

Hi,

Presence of shock wave would depend upon your boundary conditions. If pressure ratio of outlet to inlet is very low then there is less chance of having a shock in the nozzle.
