ABSTRACT	The characteristics of approximate Riemann solvers were investigated such as those of Osher and Roe,which are used as a″building block″for construction of modern shock-capturing schemes.Also a new approximate Riemann solver is proposed which is the result of an improved HLLEM scheme,satisfying the positivity and entropy condition.The data obtained indicate that this new Riemann solver can be generalized for non-equilibrium flows such as chemically reacting high-temperature one.
