Numerical Simulation of a Pollutant Transport in Lower Atmosphere Layer from Thermal Power Plants
Authors: ,
Abstract: The purpose of this work is to investigate the distribution of pollutions in the atmosphere. The fast development of the industry leads to an increase in the number of factories, plants, thermal power plants, nuclear power plants, that is why there are increasing the amount of emissions into the atmosphere. It is harmful to human health and the environment. That is why it is very important to control emissions, to keep them at a safe level for the environment. The best way to assess is the creating of the mathematical model of the gaseous substances motion. Such model includes various physical, chemical and weather factors. In the present paper is considered a model problem, which allows to validate the correctness of the chosen mathematical models and numerical solution algorithm. The model takes into account the physical parameters of the materials, allows to calculate the chemical reaction between the reactants and the distribution of mass fractions of emission depending on the wind velocity. The calculations were performed using the ANSYS Fluent software package. In the end there are given results of numerical solutions and the graphs. This task allows to test the existing mathematical model in order to create in the further more accurate three-dimensional model of the emissions distribution in the atmosphere. Ekibastuz State District Power Plant 2 was chosen as an actual physical model. It located in Ekibastuz, Kazakhstan.
