PRESSURE FLUCTUATION for Aerodynamic Noise???
I am trying to simulate aerodynamic noise generating from flow around a cavity. I have a mesh of size 16 million and I am using DES. I read in the Ansys reference guide that to calculate SPL i need Pressure fluctuation in the field. The problem lies here, can anyone please tell me how can I get pressure fluctuations. Do I have to define it in CFX pre, I tried finding it in Extra variable list, but could not find it :confused:.
The documentation describes how to do this - CFX Modelling guide/Aerodynamic Noise Analysis/Noise Strength Estimation in CFX, and then under the type of noise source you have.
