Abstract

A cavity configuration features a highly unsteady separated flow, which is characterised by an intense aero-acoustic coupling mechanism. Strong pressure oscillations produced in and around the cavity have the potential to cause structural fatigue and induce resonance phenomena inside the cavity. In this study, a novel open cavity configuration with doors attached on the sides and a length to depth ratio of 5.7 has been studied numerically using the TAU code developed by German Aerospace Center for high subsonic and supersonic flows. The turbulence is resolved partially using a hybrid RANS-LES turbulence model. The study comprises the Mach numbers (Ma) 0.8 and 1.2 with Reynolds number (Re) \(12 \times 10^{6}\). The Rossiter modes occurring in the cavity due to the feedback mechanism have been numerically computed and validated for both flow conditions using reference data from experimental measurements.
