Behavior Observation of Single Droplet in Spray Cooling

The role of water cooling is important in the steel making process. In order to obtain a desired material, temperature control in the water cooling zone, which is the final stage of the manufacturing process of thin plates and thick plates, is important. The quench point is one of the factors that determine the cooling characteristics of steel. Because the quench point is influenced by many parameters, the mechanism for determining the quench point remains unclear. In this study, we observed the elementary process of cooling using multiple droplet temperatures. The influence of droplet temperature on cooling was investigated.
