Hello All,

I want to make sure Isentropic efficiency formula in CFX.

Is that correct, to take total isentrpoic enthalpy & mass flow average for isentropic total enthalpy?

H01 = massFlowAve(Total Enthalpy in Stn Frame)@Inflow
H02 = massFlowAve(Total Enthalpy in Stn Frame)@Outflow
H02’= massFlowAve(Isentropic total Enthalpy)@Outflow

Eff = (H02’- H01)/(H02- H01)

Thanks in advance...!!!!
