WebJul 26, 2024 · For evaporating droplets, there are two main stages during the evaporation evolution: unstable evaporation with decreasing heat flux and steady evaporation with constant heat flux. In the steady stage, the interface temperature gradually becomes uniform, and convection cells at the interface disappear. WebSpray cooling of solid substrates is one of the methods used in various industrial processes such as forging, quenching or other metallurgical applications, electronics, pharmaceutical industry, medicine, or for cooling of powerful electrical devices.
