Coupled Interactions of Shock-Wave Structure with Laminar Boundary Layer in Ionizing-Argon Shock-Tube Flows.

Abstract

Analyses are made of the mutual interactions between shock structure and the sidewall laminar boundary-layer and their effects on the quasi-steady flat-plate laminar boundary layer in ionizing argon shock-tube flows. The mutual interactions are studied using effective quasi-one-dimensional equations derived from an area-averaged-flow concept in a finite-area shock tube. The effects of mass, momentum and energy non-uniforities and the wall dissipations in the ionization and relaxation regions on the argon shock structure are discussed. The new results obtained for shock structure, shock-tube laminar sidewall and quasi-steady flat-plate boundary-layer flows are compared with dual-wavelength interferometric data obtained from utias 10 cm x 18 cm Hypervelacity Shock Tube.
