The Riemann Problem for the Euler Equations,o non-linear systems of hyperbolic conservation laws. The key ingredient of the scheme is the solution of the Riemann problem. The purpose of this chapter is to provide a detailed presentation of the complete, exact solution to the Riemann problem for the one-dimensional, time-dependent Euler equati

For background on these concepts the reader may consult virtually any standard book on numerical methods for differential equations. As general references, useful textbooks are t

Random Choice and Related Methods,ems of hyperbolic conservation laws. In 1976, Chorin successfully implemented a modified version of the method, as a computational technique, to solve the Euler equations of Gas Dynamics. In essence, to implement the RCM one requires (i) exact solutions of local Riemann problems and (ii) a rand

Approximate-State Riemann Solvers,ons of times, making the Riemann problem solution process the single most demanding task in the numerical method. In Chap. 4 we provided exact Riemann solvers for the Euler equations for ideal and covolume gases. An iterative procedure is always involved and the associated computational effort may n

The HLL and HLLC Riemann Solvers,The resulting Riemann solvers have become known as HLL Riemann solvers. In this approach an ., unlike the Riemann solvers presented previously in Chaps. 4 and 9. The central idea is to assume a wave configuration for the solution that consists of two waves separating three constant states. Assuming

The Riemann Solver of Roe, . Since then, the method has not only been refined, but it has also been applied to a very large variety of physical problems. Refinements to the Roe approach were introduced by Roe and Pike , whereby the computation of the necessary items of information does not explicitly require the Ro

The Riemann Solver of Osher, Osher in 1981 and Osher and Solomon the following year . Applications to the Euler equations were published later in a paper by Osher and Chakravarthy. . Since then the scheme has gained increasing popularity, particularly within the CFD community concerned with Steady Aerodynamics;
