Hi

I am doing flow simulation from a high pressure chamber to an cv-dv nozzle, using pdf chemistry - turbulence interaction. the flow still subsonic (!!) even the stagnation values (T,velocity) are high, so the ejection velocity is very weak!!!!

please an idea!!!

Is the profile of your Convergent-Divergent nozzle Correct? You might wish to look at tutorial 7 for a quick review or to the following site www.engapplets.vt.edu/fluids/CDnozzle/cdinfo.html Or could you email me your mesh file
