| Abstract: | In this paper,a spatial fully-implicit Runge-Kutta scheme is established to solve the unsteady chemical non-equilibrium NS equations,its parallel programme frame is also presented.The techniques of multi-physical-blocks pre-processing and communication optimisation are discussed.Numerical examples have been examined on the SUNWAY cluster,the calculation on feasibility,correctness and higher parallel efficiency of the scheme have been checked. |
