Hallo everyone,

I am trying to simulate gas flow through a Laval nozzle in steady state analysis with CFX. I want to use the 1D solution of flow through a Laval nozzle as the initial values for the analysis. According to the 1D solution:

local pressure/inlet pressure = f(Mach number)

Can anyone tell me the pressure in the formula is the total pressure or the static pressure in CFX?

thanks in advance!

(p-static-exit)/(p-total-inlet).
