Note (General): Numerical methods using unstructured meshes, which are represented by the finite Element Method, caused a numerical instability in the computation of high Mach number flows with discontinuities (e.g., shock waves and contact discontinuities). In recent years, several researchers have developed solution algorithms using the unstructured meshes for high Mach number flows by introducing the upwind techniques which are well developed for the Finite Difference Method. They have proposed the several methods to specify the distribution of variables in control volumes to construct higher order upwind schemes. However, the methods seem not to be well established especially for the 'cell centered' approach. In this paper, we examine a procedure to construct higher order upwind schemes, and apply the Van Leer's flux limiter to the method. Computational results are presented to show the applicability of the method to high Mach number flows with shock waves.
