External flow velocity and synthetic jets parameters influence on cavity flow structure and acoustics characteristics using RANS/ILES

Abstract

An influence of synthetic jets on the flow in a three-dimensional cavity M219 was studied using RANS/ILES method. Calculations were performed for Mach numbers M₀ = 0.85 and M₀ = 1.5. Synthetic jets’ operating parameters such as their position, number, frequency, and amplitude were varied. An impact of these parameters and M₀ on flow in the cavity, distributions, and levels of pressure fluctuations on the cavity walls as well as the narrowband spectra of pressure fluctuations were obtained. Synthetic jets located in front of a cavity may reduce peak pressure pulsations on the cavity back wall by 37% for a subsonic external flow. Moreover, it was found that synthetic jets may decrease the second and the third modes of pressure fluctuations on the back wall both for subsonic flow and supersonic case.
