Abstract

Turbulence structure in a separation bubble formed at the leading edge of a blunt flat plate with right-angled corners was studied experimentally by means of a conditional-sampling technique. The time-mean and fluctuating velocities in the highly-turbulent, reversed-flow region were measured by a split-film sensor. Conditional-sampling technique which employs a wall-pressure fluctuation as a reference signal was successfully applied to find coherent vortex structure in the reattaching zone of the separation bubble.
