STUDY ON MECHANISMS AND MODEL OF HEAT TRANSFER IN SPRAY COOLING

LU Qiu-Min LEI Shu-Ye (Department of Thermal Engineering, Tsinghua University, Beijing 100084, China)  
The mechanism of heat transfer in spray cooling is complicated, and most theories hitherto are immature. In this paper, according to nozzle spray characteristics, energy and mass balance equations for the liquid film on heated surface were founded, and a half empirical and half analysis model involving the heat dissipation is acquired. The paper presented two heat transfer coefficients: apparent heat transfer coefficient and real heat transfer coefficient. The former is affected by spatial heat dissipation, while the latter is only related to spray momentum. Later, local heat transfer coefficients were acquired through non-boiling spray cooling experiments, and were compared with the computed value to check the heat transfer coefficient models. As a result, the model was proved to accord with the experimental results.
