Abstract

A laser schlieren method is applied to measure the density-gradient profile of the shock-tube end-wall boundary layer in argon. From measurements at different positions the expected self-similar structure of the boundary layer is well established. Corrections are made for the effects of higher-order spatial derivatives of the density on the schlieren signal. The experimental boundary-layer structure is found to agree within an error bound of 2% with the theoretical calculation based on recent accurate thermal-conductivity data, if the variation of the pressure is taken into account.
