Abstract
The conjugate heat transfer from discrete heat sources to a two-dimensional jet of a high Prandtl number fluid discharging from a slot nozzle is considered. The variation of solid and fluid properties with temperature was taken into account in the numerical simulation. The geometry of the free surface was determined iteratively. The influence of different operating parameters such as jet velocity, heat flux, plate thickness, plate material, and the location of the heat generating electronics were investigated. It was found that in addition to jet Reynolds number (Re) plate thickness and its thermal conductivity have significant influence on temperature distribution and average Nusselt number (Nu).
