How to set the velocity inlet boundary condition in the compressible flow?
 
I know the velocity boundary condition is not available in the compressible flow. But I need to set a velocity disturbance, such as V=sin(t). How can I do this? Do I need to change the velocity profile to mass flow profile and then set the mass flow boundary condition? What should I do? Help, please.

You can use velocity-inlet b.c. in compressible flow.

Thanks for your reply. Do you mean that the velocity inlet boundary conditions is also available if the incoming Much number is 1.5?
