Supersonic flow calculation

Valery Ponyavin

I use FLUENT for simulation supersonic flow around bodies of different forms. I need to simulate flow during the moving the body (bodies) into container and observe shock waves around. When I use motionless body and change surrounding velocity (using UDF for changing total pressure on boundaries) everything is OK and behavior of shock is quite reasonable. But when I trying to move the body with big velocity (1000-8000 m/s) within container with motionless air (using remeshing procedures) the results look not reasonable and no clear shocks in front of the body. For example when body moving within air with v=1000 m/sec FLUENT shows Mach number less then 1 in front of the body.

Could anyone help me with the problem? Does FLUENT capable to solve such kind of problem correctly?

Thank you,

Valery
