  • Abstract In this study, we investigated the spray cooling effect with a 35μm diameter of single micro-nozzle, atomization piezoelectric plate, on the ITO heating plate, and observed the phenomenon of water droplets during flying with different initial surface temperature (Tin = 25, 70, 110, 150 and 200 oC) and spray hight (H = 10, 20 and 30mm). Through the micro-particle image velocimeter (μPIV) and interferometric particle imaging (IPI), we can catch the droplets velocity distribution and particle size evolutional, and then the planar laser-induced fluorescence (μLIF) with Rhodamine B in a concentration of 1.5 × 10-4 M as a fluorescent dye can show the temperature change of liquid film. Finally, the change of flow field and physical phenomena at different plate temperatures and spray heights are discussed to obtain the best CHF.
