COMPUTING THE PARTICLE SETTLING VELOCITY TAKING INTO ACCOUNT THE COEFFICIENT OF DYNAMIC VISCOSITY
Journal Title: International scientific journal Science and Innovation - Year 2024, Vol 3, Issue 10
Abstract
Using a spherical coordinate system, the article creates a mathematical model of the transfer and diffusion of dangerous gaseous chemicals and fine particles in the atmosphere. The mathematical model that has been built considers the modes of operation of sources that emit dangerous compounds and gas pollutants, together with their impact on the process being studied. In contrast to the writings of other authors, each layer in time and each spatial variable's rate of particle deposition was taken into account independently. Using an implicit finite-difference technique with a high level of approximation in the time and spatial variables, a numerical solution has been constructed to solve the problem. A software tool has been constructed to conduct computer experiments based on the developed mathematical apparatus. Numerical models have demonstrated that the distribution of fine aerosols and gaseous chemical particles in the atmosphere is primarily determined by climatic conditions. The study method is impacted by various factors, including the type of vegetation present, the topography, and the characteristics of the pollutant. According to the analysis, there is a reduced absorption of pollutant particles in the summer and a higher absorption of pollutant particles during seasons with high humidity.
