Mixed convection within a ventilated square cavity having baffle at the bottom wall and heating elements at the side walls has been analyzed. The inlet opening has been set at the bottom of the left wall while the exit opening is put at the bottom of the right wall. Considering air (Pr = 0.71), dimensionless and steady form of mass, momentum and energy equations are solved by implementing proper boundary condition with the help of Galerkin method based finite element scheme. Maintaining pure mixed convection (Ri = 1), baffle length is changed from 0 to 0.95L and heaters location is varied from 0.1L to 0.7L across Re = 10 to 1000. Qualitative changes of the domain are observed with the help of streamline and isothermal plots. For quantitative comparison, average temperature, Nusselt number, pressure drop and performance index has been considered. Counteracting effects of the increase in Nusselt number and pressure drop are accounted together with the help of performance index which yielded the most economic and optimum baffle height and heaters location. Final evaluation shows that the optimum length of the baffle and the position of the heaters can perform most effectively in the range of Re = 20 – 400.
