Natural, mixed and forced convection liquid cooling of discrete heat sources in a vertical channel were investigated experimentally. Ten heat sources were flush mounted to one wall of a water filled channel, while the opposite wall was unheated. Measurements of heater surface temperatures were made for a channel Reynolds number range of - 17 00 and heat flux range of 1050 - 4500 W/m2 . In the mixed convection regime, both aiding and opposed flow were examined. Temperature patterns on the heated surface were visualized using liquid crystals.
