摘要：
This paper presents the characteristics of the breakup behavior and heat transfer of a single small droplet impinging upon a hot surface. Using the vibratory method, uniform-sized droplets of water were formed at constant intervals at room temperature and under atmospheric pressure. The breakup behavior relates well with the particular surface temperature, that is, the maximum evaporation point and the Leidenfrost point. The characteristics of heat transfer, i. e. , the heat-transfer effectiveness and the heat-transfer coefficient, are also discussed.
