Abstract

This numerical study evaluates the performances of the statistical method of Reynolds realized (RANS) in the numerical simulation of a confined swirling turbulent flow. The confrontation of the computation results with real measurements confirmed the insufficiency of this approach. This handicap is related to the complexity of the structure of the flow (non stationary, three-dimensional, various scales of turbulence.....) revealed by hybrid approach DDES k-ω _SST.
