Abstract

It has been hypothesized that drop oscillations and vortex shedding within the droplet wake affect the scavenging efficiency, E, of particles. However, no conclusive results have been presented on the effect these phenomena might have on particle scavenging. To address this need, experiments were conducted using oscillating water drops and water drops damped by the addition of glycerol. The scavenging efficiencies were measured for millimeter-sized droplets scavenging micron-sized particles. These results show that E is increased by drop oscillations where the particle diameter is large, but E is decreased by these oscillations when the particle diameter is small.
