This paper presents an investigation of seven different flux splitting algorithms for the discretization of inviscid fluxes, which are the primary source for the non-linear behavior (eg. shocks, contact discontinuities). The aim of the present work is to enhance the accuracy and robustness of CHEM, a three-dimensional flow solver, which is capable of simulating a wide range of flow conditions, including chemical non-equilibrium. Five different test cases cases are considered and thoroughly analyzed. The overall goal is to find a numerical scheme that can meet some stringent specifications of efficiency, accuracy and robustness on the widest possible spectrum of flow conditions.
