COMPLEX ASSESSMENT OF POLLUTION ZONES IN EXTREME SITUATIONS AT ENERGY FACILITIES

Abstract

Problem statement. The task of forecasting damage zones under various types of man-made load in the event of an extreme situation at a gas station is considered. Comprehensive forecasting includes the determination of areas of chemical, thermal and mechanical contamination in the event of an extreme situation at a gas station. The purpose of the article. Development of a theoretical toolkit and a package of programs for complex forecasting of chemical, thermal and chemical environmental pollution zones in the event of an extreme situation at a gas station. Methodology. Forecasting of zones of chemical, thermal and mechanical pollution of the environment in the event of an extreme situation at a gas station uses the fundamental equations of the mechanics of a solid environment: the mass transfer equation is used to calculate zones of chemical pollution; the energy equation is used to determine the zones of thermal pollution of the atmospheric air; Newton's second law is used to calculate mechanical contamination zones. Integration of modeling equations is carried out numerically. A specialized package of programs for comprehensive forecasting of environmental pollution has been created. Scientific novelty. A specialized package of programs based on developed numerical models is proposed for the assessment of chemical, thermal and mechanical pollution zones that arise in the event of an extreme situation at a gas station. On the basis of the developed numerical models, an assessment of complex environmental pollution during an extreme situation at a gas station in the city of Dnipro was carried out. Practical significance. The developed numerical models are implemented in the form of a package of application programs with a wide working range. The program package is focused on solving problems in the field of environmental safety and occupational health and safety. Determining the zones of chemical, thermal and mechanical pollution of the environment with the help of the developed program package will be important in the development of the plan for localization and liquidation of emergency situations and accidents. Conclusions. An effective tool for theoretical analysis of pollution zones formed during an extreme situation at gas stations has been created. The results of computational experiments are presented.
