Abstract

Purpose. This work involves the development of a mathematical model for the calculation of hazardous areas during emergency ammonia emissions. As an example emergency ammonia emissions at the pumping station are considered. Methodology. To solve this problem, we used the equation for the flow of ideal liquid – the equation for the velocity potential. The numerical solution of this three-dimensional equation is carried out using the Richardson method. After determining the velocity potential, the air velocity field is calculated. To predict explosive zones, a numerical solution of the three-dimensional equation of the ammonia mass transfer is used. When using this mathematical model, the non-uniform field of the wind flow velocity, the change in the vertical coefficient of atmospheric diffusion with height, the intensity of ammonia emission, and the place of release of the chemically hazardous substance are taken into account. To numerically solve the equation of ammonia transport in atmospheric air, a difference splitting scheme is used. At each step of the splitting, the unknown value of ammonia concentration is determined by the explicit formula of the point-to-point computation. Findings. Based on the developed mathematical model, a computational experiment was conducted to assess the dynamics of the formation of explosive zones in the territory of a pumping station that pumps ammonia. Information was obtained on the formation of chemical contamination zones at the pumping station. Originality. A mathematical model has been developed that allows you to quickly calculate the dynamics of the formation of explosive zones in the territory of a chemically hazardous object in case of emergency. The developed mathematical model can be used to assess the risk of toxic damage to people at a chemically hazardous facility in case of emergency. Practical value. On the basis of the developed numerical model a computer program was created, which allows to carry out serial computational experiments to determine the formation dynamics of the chemical contamination zones of atmospheric air. Standard input data are required to use the developed program. The developed numerical model can be used for serial calculations in the development of the emergency response plan for chemically hazardous facilities.
