To predict mist cooling heat transfer, it is necessary to understand systematically this phenomena. However, since there are many parameters affecting mist cooling heat transfer and the effects of these parameters are very complicated, it is still a difficult task to predict mist cooling heat transfer for actual systems. In the present paper, the effect of surface diameter on mist cooling heat transfer was experimentally investigated. To do this, the diameter of test plates was varied from 10 to 30mm. Mist cooling experiments were conducted for horizontal upward-facing surfaces made of silver. The experimental results obtained in this study show that the diameter of the plate affects the heat transfer coefficient of mist cooling in the high-temperature region corresponding to the film boiling region on the boiling curve. Next, the correlating equations for the heat transfer characteristics of mist cooling in the high-temperature region are developed accounting for the effects of volumetric droplet flow rate and surface parameters including the effect of the surface diameter. These correlating equations are in good agreement with a number of experimental data.
