Paper Abstract

A large frame schlieren image technique is presented in the paper. The technique has been applied to visualization of the boundary layer transition on the surface of the cone in the hypersonic flow. The schlieren pictures obtained from wind tunnel test are processed and measured by a micro-densitometer and a digital image processor. In terms of the computation based on a schlieren theory, the relative density profiles at various cross-sections and the transition region in the boundary layer can be shown. The measured results are compared with theoretical and other experimental results. The freestream condition in the present experiment is as follows: Mach number M=10.29. Reynolds number per meter Re/L=1.38x 107(1/m) and density ρ∝ =3.14x10-5(g/cm3).
