BOUNDARY-LAYER DEVELOPMENT AND TRANSITION DUE TO FREE-STREAM EXOTHERMIC REACTIONS IN SHOCK-INDUCED FLOWS
Abstract
A study of the effect of free-stream thermal-energy release from shock-induced exothermic reactions on boundary-layer development and transition is presented. The flow model is that of a boundary layer developing behind a moving shock wave in two-dimensional unsteady flow over a shock-tube wall. Matched sets of combustible hydrogen-oxygen-nitrogen mixtures and inert hydrogen-nitrogen mixtures were used
to obtain transition data over a range of transition Reynolds numbers from 1.1-to-2l.3 × 106. The heat-energy is shown to significantly stabilize the boundary-layer without changing its development character. A method for application of this data to flat-plate steady flows is included.
