Can anyone point me in the right direction? I need help in calculating the sound generated from saturated steam (~35 psig) passing through a gate valve and exiting to the atmosphere.
ANSI/ISA-S75-17-1989 Control Valve Aerodynamic Noise Prediction would be a good place to look.
There also is a section on valve noise in the Noise and Vibration Control Engineering: Principles and Applications by Beranek and Ver. It contains a simplified version of the above standard.
