YaoSystematic experiments were conducted for the spray cooling of high-temperature stainless steel using three different types of industrial sprays: full cone and flat hydraulic nozzles and a flat air-mist nozzle. In the present study, a wide range of mass flux (1.5–30 kg/m2sec) is covered, which has never been thoroughly investigated before. Orientations with respect to gravity and spray angle were also explored.
The data have been analyzed and correlated. The results of this study will be important to the product quality control in industries by providing a good estimation of heat flux at different mass flux, spray types, and surface temperatures, especially for spray cooling of stainless steel and other metals with similar thermal properties.
