Convective Heat Transfer from Discrete Heat Sources in a Liquid Filled Vertical Channel.

摘要

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 side of a channel wall, while the opposite wall was unheated. Measurements of heater surface temperatures were made for a channel Reynolds number range of 0 - 1700 and heat flux range of 1050 - 4500 W/m 2. In the mixed convection regime, both aiding and opposed flow were examined. Temperature patterns on the heated surface were visualized using liquid crystal....
