ashish_singh New Member ashish Join Date: May 2009 Posts: 3 Rep Power: 6	Hi, I am working on CFD simulation of overhang cavity acoustics, a problem statement given in NASA's 3rd CAA workshop. I calculated vortex-shedding frequency from well known Rossister's formula. I want to calculate Helmholtz frequency of the overhang cavity. Can anyone suggest me about the formulation for this. Thanks and Regards Ashish Singh
