Investigation of Various Mechanisms of In-cloud Scavenging of Atmospheric Aerosol and Polluted Gases



  Description
        Removal of atmospheric aerosol and gases from polluted air and gas streams by water drops is an important mass transfer process in atmospheric physics, environmental engineering and other technological applications. Scavenging by atmospheric water droplets include absorption of S02, C02, HCl, NH3, NOx, such as nitric oxide and nitrogen dioxide, chlorofluorocarbons, methane and some other gases. The goal of this research is to investigate numerically simultaneous heat and mass transfer during evaporation/condensation on the surface of a stagnant or moving droplet in the presence of inert admixtures containing non-condensable solvable gas. We also study conjugate mass transfer during absorption of a gas by a falling droplet with internal circulation.
