The formation of an aerosol by condensation of a dilute vapour in a carrier gas

Abstract

The formation of a dilute aerosol by supercooling a mixture of vapour and carrier gas is examined theoretically. It is shown how the partial differential equations of this kind of problem can be reduced approximately to a set of ordinary differential equations, much more easily handled by numerical methods. An approximate solution is obtained which shows how the average particle size depends on the rate of cooling and the time of quenching.
