구리평판재의 스프레이냉각특성 연구 = A Study on the Spray Cooling Characteristics of Hot Copper Flat Plates

다국어 초록 (Multilingual Abstract)

Spray cooling makes high temperature surface cooled rapidly by means of liquid heat or latent heat which created by spray. The spray cooling is of interest to many applicants in the industries such as continuous casting of ironworks, quenching of metal, heat sinker of space shutter, cooling of high ability electronic device, partial cooling of internal combustion emgine and grass manufacture. In order to study heat transfer characteristics of spray cooling for the purpose of uniform and soft cooling of high temperature surface, a series of experiments for a hot, horizontal copper flat plate was performed by downflow spray using flat spray nozzle. Cooling curves were measured under the various experimental conditions of flow rates and temperatures of cooling water.
