Experiments were performed to investigate the convective heat transfer from a two-dimensional slot jet of the dielectric liquid PAO to a smooth 15.2 mm by 9.5 mm film resistor surface. The effects of nozzle width, nozzle-to-plate distance, impinging velocity, and liquid properties have been examined. Heat transfer correlations and a discussion of relative parametric effects are provided.

Boiling heat transfer in a water heat pipe is investigated with the objective of relating heat flux and temperature drop across the evaporator. Nucleate boiling has been postulated as the heat transfer mechanism at and near the wall. A correlation has been obtained that relates evaporator heat flux and temperature drop to various screen-wick and working fluid properties. It is shown to agree well with other available experimental data.
