Flow Conditions near the Intersection of a Shock Wave with Solid Boundary

Hsue-shen Tsien

1. Introduction

Recent investigations by J. Ackeret, F. Feldmann, and N. Rott[1] and H. - W. Liepmann[2] on the interactions of shock and boundary layer in transonic flows have shown many novel features hitherto unrecognized. One of these new phenomena is the presence of a strong expansion zone near the solid boundary immediately behind the shock. The same situation appears also in the results of the numerical calculations of transonic flows by H. W. Emmons[3]. Since Emmons’ in vestigation is carried out without considering the viscosity and the heat conduction of the fluid, the occurrence of expansion zone after the shock must be independent of these ...
