Spray cooling has been used as a technique of heat treatment of metals in the metallurgical industry. The advent of the Thermo-Mechanical Control Process (TMCP) in the steel industry brings about a need for precise control of cooling rate. In this study, droplets that impact onto hot plate were investigated. A high-speed camera was used to observe the impact behavior of water droplets. The effects of droplet impact velocity and droplet diameter were predicted by the model. Correlating equations of the impact behavior of water droplets were proposed and compared with experimental data.
