Abstract

This paper presents a potpourri of factors which are of concern in the numerical analysis of sound generation and propagation by fluid flows. It is shown that successful computational aeroacoustics (CAA) solutions require that careful attention be given to numerical algorithms, stability considerations, and gridding. In particular, difficulties inherent in high Mach and Reynolds number viscous calculations are discussed.
