“…[18] conducted the research based on developed regional models of the process of diffusion of substances described hydrothermodynamic equation, namely the equation of molecular heat conduction in the active layer of soil, taking into account the heat balance of the underlying surface (water, earth). Developed by researcher a comprehensive mathematical model is made up of individual blocks, each of which represents a mathematical model describing the hydrothermodynamic processes in separate environmental objects.…”

In the paper, we describe a mathematical model of the spread of harmful substances in the atmospheric boundary layer, taking into account the terrain and the characteristics of the underlying surface, described by means of a system of differential equations in partial derivatives and corresponding initial and boundary conditions. The equations of motion of multicomponent air, equations for calculating the pressure and heat flow for gas and condensate are used in the model. u v w , To determine the velocities of the air mass in the atmosphere in three directions and we consider the hydrodynamic equations of Navier-Stokes, and to compute the density of substances emitted into the atmosphere, taking into account the law of conservation of mass to the fluid flow through the fixed volume we use mass continuity equation. To calculate the heat transfer in a multicomponent environment in the transfer of heat to the gas, and to determine the vapor pressure in terms of temperature, we use the equation ofMendeleev-Clapeyron. The equations are given for describing the transition of water from liquid to gaseous state and vice versa, and when gas, water vapor, liquid water and soot are thrown from the source.

The paper considers a mathematical model for research, forecasting, and management decisions on the process of spreading harmful aerosol substances in the atmosphere. When deriving a mathematical model of the object, the main weather and climatic factors affecting the process of transport and diffusion of harmful substances and the terrain of the region under consideration are taken into account. Changes in wind direction and speed are calculated using the Navier-Stokes equation of stream function and vortex velocity variables. The proposed software was implemented as a software tool in the Borland C ++ Builder environment to carry out computational experiments. The results of the performed numerical calculations are shown in the form of graphical objects.
