[CFX14]

Dear all,
I simulate a steam valve with steady state incompressible flow.
Boundary conditions are defined as follows:
inlet: Temperature and velocity
Wall: constant temperature
outlet: pressure

since in some region the mach number is greater than 0.3, i used here a total energy model. turbulence model is SST with very high resolution at the boundary layer (y+ ~ 5)

but as shown in Post-processing the wall temperature is not constant as defined.

thank you and Regards.
