Convection effect on sulfuric acid drop formation in atmosphere neighboring to a thermal power plant region

Abstract

The paper introduces the results of mathematical modeling of sulphurous anhydride condensation on condensation nuclei surface within the stated problem. The design results are given for spring and summer. It was ascertained that sulfuric acid drops are formed with slight changes at different wind speed and typical operation parameters of thermal station. The authors estimated the sizes of condensation nuclei. On their surface the drops which are capable of falling on Earth surface are formed. Air mass displacement velocity affects the acid antropogenic impurity dispersion in the air. The obtained values of sulphurous anhydride were compared with the results of calculation by one of famous techniques. The results obtained were approved by checking the difference scheme conservation and solving the test problems.
