Pressure coefficient on surface
Posted: Thu Feb 17, 2022 11:03 am
Dear all,
I saw several topics on this subject but I wanted to be sure to clarify with my version of code_saturne (6.0.4).
The "Normal_Stress" field on solid surfaces is equivalent to "Pressure" in fluid cells, unit Pa.
The "Pressure" in the fluid cells corresponds to the pressure delta between "total_pressure" and "reference total pressure".
So if I want to have the pressure coefficient on a surface it is enough to do the calculation
"Pressure coefficient = Normal_Stress/(0.5*Rho*Vinlet)"
Best Regards,
Alexandre
