PARAMETRIC STUDY OF NON-EVAPORATIVE SPRAY COOLING ON ALUMINUM PLATE: SIMULATION AND ANALYSIS

ABSTRACT
As the behavior of the spray cooling parameters, during cooling without phase change, is rarely considered and there are only little investigations on that matter, this work is focused on the influence of the parameters involved in water spraying cooling process of an aluminum plate at a temperature of 92°C. A detailed study of the effects of mass-flow rate, fluid pressure and the nozzle height above the hot plate was achieved using the version 5.2 of the COMSOL Multiphysics code. First of all, the flow rate was varied from 0.497 up to 1 L/min. Then, the inlet pressure varied from 0.7 to 2.1 bars. The influence of nozzle-to-target distance is also tested since the simulations were carried out in a wide height range (100 to 505 mm). The effect of the studied parameters on the temperature, total internal energy, convective heat flux, Reynolds number, spray distribution and velocity was investigated.
