    Performance de la Méthode de RANS dans la Simulation d'un écoulement tourbilonaire
    (Université Larbi Ben M'hidi, 2012) Bahri, Lakhdar; Belkharchouche, Adel
    Our present study is a continuity former work on the numerical simulation of an isothermal jet, turbulent and confined in a cylindrical enclosure. The objective is to study in an axisymmetric configuration, the performances of models of turbulence based on the method of the averages of the Navier-Stokes equations (RANS), namely the model k- based on the concept of turbulent viscosity and the model of the constraints of Reynolds. Each one is evaluated with two of these versions: Standard and RNG for k- and LRR and SSG for the RSM. The validation of the computation results is made for a low intensity of swirl with real measurements. The commercial computer code Fluent was used as tool
