Original abstract

The general term “spray cooling” is for the research presented here limited to the spray cooling of hot surfaces with lm boiling, starting at temperatures of about 1200 C and nishing at the Leidenfrost point where cooling intensity changes rapidly. This is typical area of secondary cooling in continuous casting. Herein, a correlation for Heat Transfer Coefcient (HTC). The most frequently used parameter of water impingement density is in the presented correlation used together with impact pressure to get good results. This study uses both water and mist nozzles. It is shown and experimentally veried why equations based only on the water impingement density cannot provide sufciently precise predictions of HTC.
