CFD Acoustic
 

Dear Friends

I'm reading T.J.Chung's "Computational fluid dynamics".

But I am still unable to understand, how to derive any acoustic data from (for example) FVM on structured non-orthogonal body-fitted grids, with which I used to work.

For example - reacting swirling flow in the combustion chambers of GE90 or F101 or Al-31FU engines

How to deal with CFD Acoustic?

Any comments will be highly appreciated
