Abstract
The present work presents the numerical analysis of the turbulent flow and heat transfer enhancement of air inside a channel of rectangular section with two baffles sequentially arranged in the top and bottom of the channel wall. Three different types of baffles are used. The governing equations based on the k-€ model with low Reynolds number used to describe the turbulence phenomenon are solved by finite volume method using SIMPLEC algorithm. The velocity profiles are obtained for all the geometry considered and for selected sections namely upstream, between baffles and near exit section. Temperature contours for all three cases are obtained. Results demonstrate that in presence of inclined baffle the heat transfer is significantly enhanced.
