Hi,

I wonder if the variable "ps" in the vortex sound equation as shown in the figure could be solved by using the additional variable, or other ways to get the "ps" in CFX.

Any suggestions would be greatly appreciated.

Please explain what you are talking about. What is a "vortex sound equation"? aero_head likes this. __________________ Note: I do not answer CFD questions by PM.
