ABSTRACT={This study deals with numerical simulation of anisothermal flows in gas pressurized solar receiver. A turbulent air flow, in a bi-periodical channel, at low Mach number and high Reynolds number is considered. A posteriori tests are performed in order to compare results of several turbulence models of large eddy simulations with a direct numerical simulation. Functional, structural and mixed models are evaluated. Dynamic and thermal integral values caracterizing the flow, as well as mean and fluctuating values of velocity and temperature are analysed.Velocity and temperature correlations are studied.}}
