Numerical investigation of the effect of baffles, placed between two parallel plates, on flow and heat transfer under condition of laminar forced convection

In this study, two-dimensional numerical analysis of fluid flow and heat transfer between two parallel plates with baffles has been carried out for laminar forced convection. Baffles have been placed in staggered arrangement in the channel. Governing equations have been solved numerically using Fluent 6.3 program. The effect of the number of baffles and Reynolds number on flow and heat transfer has been investigated for hydrodynamically fully developed and thermally developing flow. It has been seen that the number of baffles and Reynolds number has important effect on flow and heat transfer. Results have also shown that increase in the Reynolds number and baffle number causes an increase in average Nusselt number and friction factor.
