Abstract
The paper discusses the dynamics of aerosols as applied to the spread of airborne viral infections in conditions where the mutual movement of the objects under study should be taken into account. This feature should be most strongly manifested in urban environments, where various traffic flows are an integral part of the habitat of modern man. The movement of individual particles in two-dimensional geometry under the influence of gravity and friction, as well as an external electrostatic field, is considered. Within the framework of the developed model, the influence of initial conditions determined by the physiological processes of respiration and the state of the environment on the dynamics of the spread of exhaled aerosols is studied. An assessment was made of the distances over which aerosol particles can spread depending on the size and initial velocities of the particles. Larger particles have been shown to travel longer distances. While smaller particles are «frozen» into the environment and can only spread with air currents. When applied to the transmission of viral infections, this means completely different types of virus transportation depending on the size and type of dispersed phase. The results obtained were applied to the analysis of the characteristics of spread for viruses in metro.
