Abstract
The present study reports of passive technique to enhance the cavity-induced pressure oscillations by modifying the cavity leading edge configuration. 3 (three) leading edge geometries namely circular-contoured, slanted and circular contour on 30° slant edge were used in the study. The density-based algorithm in ANSYS Fluent 13.0 was used to solve the time dependent Navier-Stokes equations. The SST k-ω model was used for modeling the turbulence within an unstructured mesh solver. Validation of the computational code used was accomplished and the results showed a good agreement between the numerical simulation and experimental data. The study comprised the analysis of pressure oscillations in and after the cavity. The modification of cavity leading edge shown influencing to the pressure fluctuations.
