The Effect of Nozzle Collar on Single Phase and Boiling Heat Transfer by Planar Impinging Jet
평면 충돌제트에서 노즐 깃이 단상 및 비등 열전달에 미치는 영향

Abstract
The water jet impingement cooling is one of the techniques to remove heat from high heat flux equipments. We investigate the local heat transfer of the confined water impinging jet and the effect of nozzle collar to enhance the heat transfer in the free surface jet and submerged jet. Boiling is initiated from the furthest downstream and the wall temperature increase is reduced with developing boiling, forming the flat temperature distributions. The reduction in the nozzle-to-surface distance for
