How can I model Muffler radiation taking into account flow and thermal effects

Ducts and mufflers come into contact with gases that flow through from source to the open environment. This flow exhibits a mean flow component and an acoustic pressure component which results in convected acoustic wave propagation.

See how VA One working with an embedded OpenFOAM CFD solver can accurately predict the effect of gas flow in ducts to provide increased accuracy of cavity response peaks.
