Numerical Solution of the Problem of Hypersonic Flow past a Thin Plate

Numerical Solution of the Problem of Hypersonic Flow past a Thin Plate The problem of hypersonic flow past an absolutely thin edge is considered. The solution is obtained using a model kinetic equation for polyatomic gases. The method of the problem solution, which makes it possible to distinguish the discontinuity of the molecule distribution in the velocity space, is described. The distribution of the normal stress over the plate surface and above it is calculated. The results obtained are in good agreement with the experimental data. It is shown that a disturbed flow region arises ahead of the thin edge of a plate in hypersonic flow http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fluid Dynamics Springer Journals

Abstract

The problem of hypersonic flow past an absolutely thin edge is considered. The solution is obtained using a model kinetic equation for polyatomic gases. The method of the problem solution, which makes it possible to distinguish the discontinuity of the molecule distribution in the velocity space, is described. The distribution of the normal stress over the plate surface and above it is calculated. The results obtained are in good agreement with the experimental data. It is shown that a disturbed flow region arises ahead of the thin edge of a plate in hypersonic flow
