Effect of Total Temperature on Boundary-Layer Stability at Mach 6

This study examines the stability of the hypersonic boundary-layer flow over a cone as total temperature was varied and Mach number, Re, and T(w)T(0) were held constant. With nondimensional parameters held constant, both experiment and theory show an increase in boundary-layer stability with increas...

Zusammenfassung:	This study examines the stability of the hypersonic boundary-layer flow over a cone as total temperature was varied and Mach number, Re, and T(w)T(0) were held constant. With nondimensional parameters held constant, both experiment and theory show an increase in boundary-layer stability with increased total temperature. This absence of dynamic similarity indicates the importance of considering total temperature effects even in nonreacting gas flows. (CSA)
