Numerical Investigation of Supersonic Turbulent Flow Over Open Cavities

The study of cavity flow is one the most important research topics unsteady aerodynamics. Supersonic turbulent flows over a are mostly encountered in missiles, turbomachinery, and high-speed aircraft. turbulence inside gives rise to excess drag, acoustic waves, pressure fluctuations, vibrations which may lead numerous problems like fuel consumption, failure missile trajectory or mechanical parts, aerodynamic heating. We conduct numerical simulations investigate compare our results existing experimental data show quantitative validation. then effect Mach number supersonic on contours vortical structures subsequent other parameters waves. Thereafter, we propose two modifications geometry, a) slanted edges b) smoothened corners with edges, improve performance. ANSYS ICEM tool has been used for fine mesh generation geometry all simulation was run fluent software. K omega SST model as it can capture near wall property reasonable accuracy grid independence carried out find correct solution Navier Stokes equation proceeding by solver. contours, streamline pattern, coefficient distribution sound level (SPL) found compared both modified unmodified open at different number. suggested significant improvement designs mean distributions.
