Based on multi-component Navier-stokes equations, Weiss–Smith matrix preconditioning method is implemented within pseudo-time derivative term. AUSM+-up family schemes and LU-SGS implicit iterative method were used to solve chemical reacting flows at all speeds and were compared with experimental data and theoretical value. Through a comparison of calculation with available numerical and experimental data and theoretical value in literature, the results showed that the preconditioning algorithm can be applied efficiently to the reacting flows at all speeds. All these works built foundations for further application of aeroengine.
