原始语种摘要: This manuscript presents a numerical analysis of fluid flow and heat transfer in rectangular cross section channels with and without baffles using air as the working fluid at Reynolds numbers ranging from 12,000 to 32,000. Four various channel geometries were studied in this analysis. In the first case, a smooth channel with no baffle was analyzed. In the second case, a flat rectangular baffled channel was investigated, and in the third case, S-shaped baffled channels were examined (i.e., S-baffles pointed towards the upstream end: called S-upstream baffles; and S-baffles pointed towards the downstream end: called S-downstream baffles). The Commercial CFD software FLUENT was employed to simulate the air flow and thermal aspects in the whole domain investigated based on finite volume...
