"abstract": "Steady state experiments have been conducted for\nnatural and mixed convection heat transfer, from five different sized\nprotruding discrete heat sources, placed at the bottom position on a\nPCB and mounted on a vertical channel. The characteristic length (\nLh ) of heat sources vary from 0.005 to 0.011 m. The study has been\ndone for different range of Reynolds number and modified Grashof\nnumber. From the experiment, the surface temperature distribution\nand the Nusselt number of discrete heat sources have been obtained\nand the effects of Reynold number and Richardson number on them\nhave been discussed. The objective is to find the rate of heat\ndissipation from heat sources, by placing them at the bottom position\non a PCB and to compare both modes of cooling of heat sources.",
