INVESTIGATION OF WATER DROPLET COALESCENCE
Abstract
The coalescence of two colliding water drops was studied by determining the surface deformation of the half-drops before coalescence in a controlled atmosphere. The surface deformation and delay time before coalescence were determined at two impact velocities, at approximately zero, 50 and 97 percent relative humidity, and at an ambient temperature of approximately 27C. The experimental results indicate that the delay time before coalescence increases with higher humidities in both the slow and rapid collisions. At the same humidity and temperature the delay time is less in the slow collision than in the rapid collision. An electric potential difference between the drops decreases the delay time in coalescence and greatly affects the surface deformation.
