Interaction between the Unsteady Boundary Layer and Inviscid Hot Flow in a Shock Tube

Abstract

A numerical calculation is presented for the flow in a low-pressure shock tube. The evolution of the hot flow quantities due to mutual interaction between the boundary layer and inviscid hot flow are taken into account. A better knowledge of the unsteady evolution of this hot flow is so obtained, including the distribution of all parameters at the limiting regime. The computational results, with Argon as a driven gas, are in agreement with the different experimental results at usual measurement stations.
