High-Resolution Finite Volume Methods for Acoustics in a Rapidly-Varying
Tiernan Fogarty and Randall J. LeVeque
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".
