Abstract
Experimental measurements are presented for collision efficiencies of highly charged droplets. The drop sizes studied range in radius from 10 to 25 μm and carry charges of the order of 10−4 esu. Measured collision efficiencies greater than 100 agreed well with those predicted by Paluch's analytical solution for collision efficiency upper limit. For smaller values, the collision efficiencies predicted from Davis and from Davis and Sartor exceeded those measured.
