Evaporation of a water droplet deposited on a hot high thermal conductivity solid surface

A model is presented that predicts major features of the evaporation of water droplets deposited on a hot nonporous solid surface. In the temperature range of interest, nucleate boiling heat transfer is fully suppressed, hence the model is only concerned with the evaporative process. In the model, the solid material is assumed to have high thermal conductivity and diffusivity, so that the surface temperature under the water droplet can be considered uniform. The temperature of the portion of a larger solid surface covered by the liquid is calculated from the classic solution for contact temperature between two semi-infinite bodies
