“…Heindel et al [19,20] studied coupled conduction and natural convection transport within 2-and 3-D, discretely heated cavities. Sun and Emery [21] examined conjugate natural convection heat transfer in a 2-D, airfiled enclosure containing discrete internal heat sources and an internal baffle. Kimura et al [22] analytically and experimentally investigated conjugate natural convection heat transfer from a vertical plate for which three different materials including copper, stainless steal and ceramic were used.…”
