The objective of this effort is to assess the accuracy of a recently developed code, turf2, to predict transient effects caused by a shock wave moving over a sand bed, and diffracting over an obstacle on the surface and in a hot layer of gas. during 1984, turf2 two-phase flow boundary conditions and… More

This proposal is to support nasa's program in the field of computer simulations of turbulent flows over complex geometries. the innovative turbulence model designed at ames research center by mansour, kim and moin (1987), called the mkm model, will be extended to treat separated flows. the mkm model… More

The proposed work will improve the ability of turbulence models to solve transition and turbulence phenomena in the hypersonic regime. the state of the art, ups computer code,developed at nasa-ames research center by lawrence et al. (1987), will be the basic numerical tool. two-equation turbulence… More
