Pressure coefficient on surface

Post by Alexandre »

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
