Assessment of an approach to generating inflow synthetic turbulence for large eddy simulations of complex turbulent flows
St. Petersburg State Polytechnic University St. Petersburg, Russia
An approach to generating inflow synthetic turbulence recently developed by the authors has been applied to zonal Reynolds-Averaged Navier-Stokes (RANS) / Large Eddy Simulations (LES) of two complex turbulent flows: flow over a wall-mounted hump and hydrofoil trailing edge flow, and to a LES of a flow in a three-dimensional (3D) diffuser. The results show that the zonal RANS-LES approach with synthetic turbulence at the interface is in excellent agreement with experimental data for hump and trailing edge flows. For the diffuser flow, it is shown that results depend significantly on the RANS model used to provide averaged velocity and Reynolds stresses at the inlet.
