2-D double wedge in Hypersonic flow
 

Hi,
I am modeling a 2-D wedge in hyper-sonic flow having the following free-stream conditions:
Mach no-9.59
Temperature-185.6k
Pressure-36.5Pa
I have used the following setup in fluent post:
Desity based
fluid-Ideal gas
standard initialization from farfield
I tried running the 1000 iterations initially...in which the continuity and energy equations are hardly changing while the x velocity is having a negative slope(convergence), the y velocity is having a positive slope(divergence)..i having tried reducing the cfl value...it is showing the same trend as I increase the number of Iteration...plz sugest how should I proceed:(:(:(
