Modelling the Spatial Distribution of Industrial Facilities and Green Areas to Reduce the Ecological Footprint

Abstract

The work solves conjugated problems of a stationary and non-stationary nature for the processes of transfer and diffusion of harmful substances into the atmosphere emitted by industrial facilities to protect the ecology and environment from man-made factors. When mathematically modelling mass transfer in air, absorption coefficients were considered depending on climatic conditions and external disturbances, as well as adhesion coefficients of aerosol particles with vegetation and other weather and climatic factors. Analytical solutions and dual functionality were obtained, and solutions have been developed to optimize the location of industrial facilities in the region from the perspective of economic development and environmental protection. Numerical calculations have shown that the efficiency of particle capture by vegetation is a key factor depending on the type and size of vegetation and varying throughout the year. Experiments have confirmed that the concentration of harmful substances in the ground layer of the atmosphere decreases with increasing coefficients of absorption and capture of particles by vegetation. Computational experiments carried out on a computer have established that with an increase in the diffusion coefficient, the zone of distribution of pollutants expands.
