Abstract

Numerical simulations of three-dimensional unsteady cavity flow at Mach number 0.85 were conducted by using delayed detached eddy simulation (DDES) and unsteady RANS (URANS) methods based on the SST turbulence model. The gained static pressure, sound pressure level (SPL) and power spectral of pressure fluctuations at the cavity bottom by both methods compared well with experimental and other CFD results. Compared with URANS, DDES is more suitable for modeling flow details such as shear layer instability and fine scale turbulence structures, and also for high frequency pressure fluctuation capture. The simulated cavity flow can be identified as transitional flow by checking the time averaged flow characteristics. Meanwhile, complicated three-dimensional flow structures are also captured by both DDES and URANS, the effects of which are discussed.
