Hypersonic viscous flow computations

A brief description of the work currently underway on hypersonic viscous flow computations, based on the solution of thin-layer Navier-Stokes equations employing upwind TVD schemes, is presented.Both van Leer and Roe schemes are considered.Some representative computational results presented indicate that these schemes are quite robust and can provide sharp description of the shocks.The importance of parallel computing on machines like Flosolver and the use of implicit techniques to accelerate the computations is emphasized. The future direction of hypersonic research is indicated
