Lalmi Faculty of exact sciences, natural sciences and life, Larbi Ben Mhidi University, Oeb Algeria R. Hadef AJME201533A5 10.12691/ajme-3-3A-5 2015 05 20 2015 06 22 2015 07 14 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.
