Approximate Riemann Solvers, Godunov Schemes, and Contact
Discontinuities
Burton Wendroff
Abstract:
A two-dimensional (2D) 9-state approximate Riemann solver and corresponding 2D
Godunov scheme are developed. A contact-preserving form of Lax-Friedrichs in
one and two dimensions is presented. Numerical examples are given for several
one and two-dimensional Riemann problems.
