Numerical Investigations on Supersonic Fluid Flow past a Cavity Relating Coefficient of Pressure and Density Fields

Authors(1) :-Dr. Nirmal Kumar Kund

A very precise numerical model is developed to work out supersonic flow past a 3D open cavity. The examinations of supersonic flow past the 3D open cavity possessing length-to-depth ratio of 2, comprise the supersonic free-stream Mach number of 2 besides the flow Reynolds number of 105. The numerical simulation has been executed through the Large Eddy Simulation (LES) method. The Smagorinky model is engaged for this exercise. The simulation predictions have been accessed in the form of both aeroacoustic effect symbolised by the coefficient of pressure (Cp) and the cavity flow-field epitomized by the density contour. The grid independence test relating to the coefficient of pressure has also been accomplished. The LES model enables to estimate all the vital flow behaviors of the open cavity flow. Furthermore, the feedback loop mechanism of the open cavity flow has also been discussed. Very large recirculation is witnessed within the open cavity and therefore these require to be suppressed. Nevertheless, the combination of a spoiler at the leading edge of the open cavity is also planned for the future to alter the flow behaviors within the open cavity, which can also bring about the reduction in the recirculation within the open cavity as well.
