Heat Transfer Characteristics in Wall Jet Region with Impinging Water Jet
충돌수분류에 의한 벽면분류 영역에서의 전열특성
Abstract
The purpose of this investigation is to study heat transfer characteristics in wall jet region on a flat plate caused by upward impinging water jet. In the wall jet region, heat transfer results by impinging water jet are being compared with the ones with supplementary water. As the radius increases, the heat transfer coefficient in the wall jet region consquently decreases, but decreasing nozzle-heat plate distance, the reduction rate increases. The experimental equation is expressed as follows :
