EСOLOGICAL FORECASTING OF ADMIXTURES IN AN OPEN TURBULENT FLOW BASED ON CORRELATION FUNCTION AND TURBULENT DIFFUSION COEFFICIENT
Pages 141-149
Operation of anthropogenic industrial facilities misbalances the natural environment. The study of interaction between production facilities and the natural environment is performed using mathematical modeling techniques. In ecological forecasting, mathematical models are used to simulate the pattern of outspread of various pollutions into the air, water and soils. Mathematical models are employed to identify changes of environmental parameters and to measure the environmental friendliness of production processes.The research into projected or existing waste generation patterns can be used to assess or predict the scope of damage inflicted on the nature and the society and to provide recommendations concerning selection of process technologies. Any flow of fluid or gas is turbulent in almost every case, while the presence of solid particles reduces the amplitude of pulsation speed in a turbulent flow. The calculation of time or distance of travel of contaminants is based on the coefficient of turbulent diffusion. The coefficient of turbulent diffusion in a turbulent flow is no constant value. MGSU laboratory of hydraulics conducted experimental studies of open streams in a rectangular channel to identify patterns of correlation curves and limitations of applicability of well-known formulas. In furtherance of three main geometric constraints of patterns of correlation curves, turbulent flows can be conditionally divided into three types. Types of correlation functions and shapes of vortices are driven by the distance at which the mixture will spread over the turbulent flow. Therefore, the tasks of the theory of diffusion can be classified depending on the purposes of research.
