Natural Convection in a Cavity with Orthogonal Heat-Generating Baffles of Different Lengths
ABSTRACT
Natural convection in a closed square cavity induced by two mutually orthogonal heat-generating baffles is considered. A numerical investigation is made to understand the effect of baffle dimensions on the resulting heat transfer characteristics. The coupled nonlinear governing equations were solved by the finite difference method using the Alternating Direction Implicit technique and the Successive Over-Relaxation method. The results obtained indicate that the flow and temperature fields strongly depend on the dimensions of heat-generating baffles. It is found that when both baffles are mounted inside the cavity an increase in the length of any of the baffle results in a proportionate increase in the overall heat transfer rate. But no significant changes in the overall heat transfer rate occur for different positions of the baffles. When the vertical baffles is mounted on the cavity wall it extracts heat energy from the cavity and behaves like a cold wall for an increase in its length. The study provides additional basic design information during fabrication in microelectronics industry.
