A wave propagation method for three-dimensional hyperbolic conservation laws

J.O. Langseth and R.J. LeVeque


Abstract: A class of wave propagation algorithms for three-dimensional conservation laws is developed. These unsplit finite volume methods are based on solving one-dimensional Riemann problems at the cell interfaces and applying flux-limiter functions to suppress oscillations arising from second derivative terms. Waves emanating from the Riemann problem are further split by solving Riemann problems in the transverse direction to model cross-derivative terms. Due to proper upwinding, the method is stable for Courant numbers up to one. Several examples using the Euler equations are included.
