摘要:Free convection in a partially foam-filled enclosure is theoretically investigated. Two independent approaches are undertaken. Scale analysis has been conducted along with a thermal resistance network model to predict the performance of metal foams as heat sinks to remove heat from a horizontal heated plate. Results from scale analysis were used to predict the flow regime transition from that of the viscous drag-dominated to that of form-drag dominated flow. Predictions from the two approaches are then cross-validated and compared against available experimental data in the literature. A good degree of agreement was observed. Finally, using the theoretical models, a parametric study was conducted to investigate the effects of different parameters on the Nusselt number.
