The wall boundary layer behind a moving shock wave

Abstract

If a shock wave advances into a stationary fluid bounded by a wall, a boundary layer is established along the wall behind the wave. Some characteristics of this boundary layer are investigated herein. The problem is reduced to a steady state by using a coordinate system wherein the shock is stationary (fig. 1). In this coordinate system the fluid and wall both approach the shock with the same velocity, u _w . The shock reduces the fluid velocity to u _e while the wall velocity is unaffected, resulting in a boundary layer for x > 0. The laminar case has been treated in [1] to [8]and the turbulent case has been treated in [3]. The purposes of the present paper Fig. 1. are to present modifications of the solutions of [2] and [3] which make them more applicable for the strong wave case, to investigate further the wall surface temperature variation and to discuss some experimental transition results.
