Abstract

Impacts on the spatial and temporal resolutions are discussed through the twodimensional model problem of jet impinging which is proposed by the present authors and Housman et al.[AIAA paper 2011-3650,2011]. The result shows that the high-resolution schemes improve the resolution of fine structures of vortices, though even a conventional scheme can predict the blast waves well. For solving the fine structure of vortices, high-order scheme is more than 10 times as efficient as conventional scheme.
