Abstract

A generalized expression for computing coagulation rates of aerosol by differential impaction is developed. This is solved for an aerosol flow past a cylinder and in an impactor. Potential flow conditions are used to obtain the velocity field. Significant enhancement of deposition of small particles occurs under high aerosol number concentration situations. Upper limits on number concentrations that can be used for unbiased sampling in impactors are developed.
