On an improved calculation method of shock-tube flow
Abstract
The problem of interaction between the boundary-layer and the inviscid flow of the test gas in a classical shock-tube has been reexamined. A numerical determination of the flow parameters has been carried out by a method of characteristics for the inviscid flow and by a local similarity method for the boundary-layer. The computation is performed along successive time-constant lines (Hartree's method) and takes into account a mass loss term for the inviscid flow and the spatial pressure gradient for the boundary-layer. The results give simultaneously the evolution of the shock-wave, the test time and the spatial-temporal variations of the different test gas flow parameters. Results are in good agreement with those of Mirels (1971).
