Brownian coagulation of like-charged aerosol particles

Abstract

In this study we explore the role of Brownian coagulation on bidisperse like-charged spherical particles interacting via non-continuum hydrodynamics interactions. It is well established in the existing literature that van der Waals interactions enhance the coagulation rate. However, the role of near-field attractive electrostatic forces on the pair interactions of like-charged aerosols is relatively less explored. We have found that electrostatic interactions enhance the coagulation rate between like-charged Brownian particles while interacting through non-continuum hydrodynamics.
