Several Aerospace Applications of Computational Aeroacoustics

This paper describes some recent Computational Aeroacoustics (CAA) simulations of problems of practical importance. Many previous CAA studies have emphasized the development of algorithms and their application to relatively simple model problems. Examples of computational aeroacoustic calculations are given for ducted fans, rotors, cavities, engine inlet liners, and jets. The need for three-dimensional, non-linear simulations and the feasibility of such solutions on high performance parallel computers is emphasized.
