Effects of drop size and drop velocity on cooling characteristics of sprays

The effect of drop size and drop velocity on the cooling characteristics of sprays was investigated in this study. Various line pressures and distances from the nozzle were used to obtain Sauter mean drop sizes between 200 and 300 microns, and velocities between 80 and 130 m/s. Local heat flux data were collected using the temperature profile generated in the heated billet as the billet cooled from above 400° C to below 100° C. Experimental results show an increase in heat flux with increasing velocity for local mass fluxes of 34 and 53 g/cm2 s, for both maximum heat flux and for the heat flux at a surface temperature of 300° C. Also, effective heat flux decreased with increasing droplet Sauter mean diameter over the range of test conditions.
