Research Abstract

We studied to clarify thin-film evaporation heat transfer phenomena and to increase evaporation heat transfer performance. In basic research, we devised and optimized the new-type surface geometry of the multilayer-meshed surface and the cross-grooved surface. We measured evaporation heat transfer performance of the surfaces supplied with thin liquid film by bubbles. In application study, we studied the electronics cooling and the solar collector. As the results, we found the optimum conditions to increase the evaporation heat transfer performance.
