We present calculation of compressible flow based on solving the Navier-Stokes equations at equal intervals in Cartesian coordinate system. For a fundamental understanding of unsteady flow, we apply the multi-directional upwind finite difference method to the compressible flow past bluff bodies of various shapes. In order to catch the complicated nature of flows around bluff bodies, it is effective to use the multi-directional upwind finite difference method for all the space derivative terms.
