| Abstract | The determining effect of six dimensionless groups on the maxinlum drop-diameter was studied for the atomization of je t s of ethanol or water injected into nitrogen or helium gas s t reams cocurrent ly or into still air. Values of the ratio of orifice diameter to maximum drop-diameter D,/D, were obtained from photomicrographs of the sprays and related to the dimensionless groups a s follows: " Do f(Bo, ReL, Re ,WeL, We , Ac) Dm g g where Bo is the ratio of hydrostatic to surface-tension forces and Ac is an aerodynamic-acceleration to surface-tension ratio. ReL, Reg, WeL, and We a re the liquid-jet and gas-stream Reynolds and Weber numbers, respectively. Liquid-injection velocities covered a range of nearly 0 to 6250 cm/sec. Gas-stream velocities were varied from the still-air condition to helium-gas velocities of 14 000 cm/sec. Gasstream accelerations ranged from 833 000 to 19 200 000 cm/sec2, and decelerations of 672 000 to 4 880 000 cm/sec2. g |
