Abstract

This paper presents a numerical study to investigate a deep cavity flow, in order to better understand the underlying mechanisms involved in it, such as flow dynamics, heat transfer, and aeroacoustics. A 2-D Unsteady Reynolds Averaged Navier Stokes model (URANS) was implemented using an SST k-ω turbulence closure simulated over a rectangular deep cavity. Previous experimental results were used to validate the numerical results, to confirm the accuracy of the flow field patterns reproduced. Both controlled and uncontrolled cases were analyzed. Heat transfer was also investigated on both configurations, showing the effect of cavity geometry and inlet conditions on heat transfer along heated cavity walls at 353.15K and 393.15K. An increase up to 7.9dB in sound pressure levels was detected due to walls heating, while analyzing the relation between heat and acoustics. Results were focusing on the effect of flow control and heat on the cavity flow behavior, offering new insights for optimizing aerodynamic performance and noise mitigation in various engineering applications.
