Flow Visualization of High-speed Cavity Flows
Abstract eng: Experimental investigations are conducted on cavity flows at Mach 0.6. Flow visualization techniques, including surface oil flow, two- and three-component Particle Image Velocity (PIV), along with fluctuating surface pressure measurements are performed on a full-span and a finite-span cavity with a length-to-depth ratio (L / D) of 6 but different width-to-depth ratios (W/ D) of 3.85 and 2, respectively. The results provide comparisons between these two kinds of cavity flows showing that they share some global flow features. However, higher velocity fluctuations and pressure fluctuations are observed in the full-span cavity.
