Experimental Study of Disturbances in Transitional and Turbulent Hypersonic Boundary Layers

Abstract

cf = skin-friction coefficient f = frequency, Hz k = roughness height M = Mach number P0 = total pressure, kPa q = heat flux, W=m Rex = Reynolds number Re1 = unit Reynolds number, m 1 T = temperature, K T0 = stagnation temperature, K u = velocity along the cone surface, m=s u = wall friction velocity, m=s X = longitudinal coordinate measured along the cone surface, mm = kinematic viscosity, m=s = density, kg=m = shear stress, N=m
