Advances in High-Resolution Schemes for Computational Acoustics on General Geometries

Abstract

A high order compact-differencing and Pade-type filtering algorithm, coupled with either the standard fourth-order Runge-Kutta scheme or with a sub-iterative implicit method is developed and implemented to simulate aeroacoustic phenomena on curvilinear geometries. Several issues pertinent to the use of such schemes are addressed.
