Hello, I am trying to simulate a supersonic intake in fluent with different mach numbers. Pressure-far-field and pressure outlet boundary conditions are selected. In the pressure far-field I need to give mach number and gauge pressure. The operating pressure is zero.Ideal gas law and Sutherland are selected.Can you describe how can i compute the gauge pressure for different mach number, which relations should ı use? Thank you.

Have a look at the various NACA examples in Help and Learning. They should contain the various equations you need.
