Abstract

An implicit hybrid Flux Vector Splitting scheme for unsteady flows with strong shock waves is presented. The hybrid FVS scheme is constructed by a combination of flux vector splitting and second-order artificial dissipation. This scheme is implemented in conjunction with an implicit unfactored method. Computations are performed for unsteady shock-wave diffraction over a cylinder and the interaction of a shock wave with a square cavity. Comparisons are presented with other numerical and experimental results from literature, including recent unstructured adaptive-grid computations. Emphasis is given on the accurate prediction of the unsteady pressure loads since this is of interest in engineering applications related to explosions and fluid-structure interaction.
