Mathematical simulation of aeration and diffusion processes in the air-water interface

Abstract

This paper deals with problem of water aeration. Water aeration is important factor that influences process of open water self-purification. Aeration first of all depends on purely physical diffusion process taking place in the interface between air and water. Specific of the character of these processes was discussed. Also attention was paid to the features and behavior of air and water bubbles created in the falling water turbulence flow. The final goal of this paper was to describe these processes mathematically. Mathematical simulation kinetic equations describing air and water bubbles adsorption and desorption processes where proposed. The results show good coincidence with experimental data obtained by independent researchers.
