This paper deals with transient heat transfer for a water drop impinging on a heated surface in the surface temperature range from maximum boiling rate point to the non-wetting region. The boiling curves were obtained by analyzing the transient temperature variation inside the heated surface taking account of the time variation of the area covered by the drop. By comparing the boiling curves obtained in this way with that for pool boiling, the heat flux in both cases increases with increasing subcooling, while the maximum heat flux point of the boiling curve was located on an extension of the nucleate pool boiling curve and that the boiling heat transfer for a drop on the heated surface was classified into four types according to the degree of subcooling and to the heated surface temperature.
