Abstract
Inertial impaction and electrostatic attraction are generally the two most important mechanisms for the collection of charged micron-sized particles by charged droplets. An experiment was carried out to determine the collision efficiencies of charged 142-μm-radius water droplets for charged micron-sized particles under different values of the electrostatic force. Experimental results agree well with a trajectory model that used a numerically derived flow field for the 142-μm-radius droplets.
