I am trying to solve a supersonic flow of M=1.71 (472 m/s)over a cavity in side a test-section. I gave the inlet as pressure inlet and outlet as pressure outlet. I calculated the static pressure and temperature exactly. In MATERAILS i selected ideal-gas and sutherland formula.
But when i m tryin to initialise at the inlet, the velocity is 392 m/s only i.e M=1.4. that means i m not able to get M=1.71 at the inlet, whicih i specified in boundary conditions. where m i goin wrong. can somebdy help me pls... thanks ravi |
