Investigation on separated and unseparated transonic convex-corner flows

研究成果: Paper

摘要

A naturally developed turbulent boundary layer past convex comers was studied. Mean surface pressure in Mach 0.64 and 0.83 indicated strong inviscid-viscous interactions. Interaction region increased with Mach number and convex-comer angle. Also, unsteadiness of the interactions was characterized by an intermittent region and local peak pressure fluctuation, which was due to the amplification of lower frequency components as shown in power spectra. At higher convex-comer angle (M = 0.83 and α = 15°) the boundary layer was separated. Unsteady shock motion induced intense surface pressure fluctuation which spectrum was centered at about 780 Hz.
