Mixed and forced convection liquid cooling of discrete heat sources in a vertical channel was investigated. Ten heat sources were flush mounted to one of the plexiglass channel walls, while the opposite wall was insulated. Measurements of heater surface temperatures were made for a channel Reynolds number rage of 500-7300 and heat flux range of 510-2700 W/m(2). Temperature patterns on the heated surface were visualized using liquid crystals. Effects of flow pulsations on heat transfer were also investigated in the 0-1.25 Hz range.
