For simplicity we will restrict the following presentation to flows with statistically two space dimensions, i.e., a variable vector W = (Ο, ΟU, ΟV, Ο E, Ο R 11 , Ο R 22 , Ο R 33 , Ο R 12 ) t , such that we can write the system in matrix-vector notation
We show that a simple relaxation scheme of the type proposed by Jin and Xin [Comm. Pure Appl. Math. 48, 235 (1995)] can be reinterpreted as defining a particular approximate Riemann solver for the original system of m conservation laws. Based on this observation, a more general class of approximate
A number of Riemann solvers are proposed for the solution of the Riemann problem in a compressible liquid. Both the Tait and Tammann equations of state are used to describe the liquid. Along with exact Riemann solvers, a detailed description of a primitive variable Riemann solver, a two-shock Rieman
