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.

I have no idea what that equation is or what the symbols mean. Please explain what you are talking about. What is a "vortex sound equation"?
