High-Resolution Finite Volume Methods for Acoustics in a Rapidly-Varying Heterogeneous Medium

Tiernan Fogarty and Randall J. LeVeque

Abstract: Behavior of acoustic waves in a rapidly-varying heterogeneous medium may be investigated analytically via various homogenization theories. Alternatively, one can solve the heterogeneous equations directly with a numerical method. Although a numerical solution can be difficult with standard methods, we have found the equations can be solved directly using the high-resolution multi-dimensional finite volume methods of CLAWPACK, which are based on solving "Riemann Problems".
