Hello, 

You can refer to this tutorial: Chapter 7: Modeling Transient Compressible Flow (ansys.com)

You can use high speed numerics ( see the user's guide for more info) to get a stable solution. The Mach number associated with pressure values can also be run using the pressure based solver. I suggest trying wth PBNS.
