Arvind Pallela

Could you be more specific with the model?

It usually depends on the inlet pressure and the operating pressures you have provided and the air properties you have used. It could also the turbulence intensity being provided could affect the Mach number.

Shiva Kumar

Thank you, Mr. Arvind. Actually, I am simulating a 2D cascade of supersonic compressor blades in fluent. I am using pressure far field inlet condition and pressure outlet condition. At the inlet I need to specify P1 and M1 along with T1. After the solution converges, the inlet parameters change when I am checking in the results though the outlet condition I provided remain as it is. But I don't want my inlet parameter to be changed.

Please check if you are giving the exact value of pressure as 101325 Pa and also use hydraulic intensity in the inlet condition and specify the hydraulic diameter for accuracy. If problem still persists share an image so that I could check.
