Improving the scavenging kernel of aerosol particles by small water drops EL2014-015/C2015-058 | 2015Scavenging aerosol particles by means of water sprays is an efficient way of removing hazardous dust from the atmosphere. Starting from the work of Wang et al. (1978), we propose to extend its formulation of a theoretical scavenging kernel to particles…
