Abstract

In this study, we numerically simulated of the influence of shape and height of baffle on heat transfer by mixed convection in a channel. The bottom wall of the channel is heated by a constant heat flux, the other walls are adiabatic. The finite volume method is used to solve the governing equations. The Reynolds number Re between 50 and 300. The Grashof number Gr is fixed at 4 10 , and the Prandtl number Pr is kept constant 0.71. The results obtained in this study show that the transfer is louder for the low height irrespective of the shape of baffles, in addition, the number of average Nusselt Nuav takes maximum values for the triangular configuration.
