USE OF MATHEMATICAL MODELS IN THE PROBLEMS OF ASSESSING THE CONSEQUENCES OF EXTREME SITUATIONS ON INDUSTRIAL FACILITIES

Abstract

The report considers some classes of numerical models that were built to predict the consequences of emergencies at industrial enterprises. The first class of models has been developed to predict chemical air pollution in case of accidental emissions of toxic substances. Modeling is carried out on the basis of the fundamental equations of aerodynamics and mass transfer. Difference splitting schemes are used for the numerical solution of the modeling equations. The second class of numerical models has been developed to assess the risk of chemical injury to people in industrial rooms. The third class of models was developed to assess the risk of injury to people when a shock wave moves. To solve this problem Euler equations were used. The fourth class of models was developed to predict river pollution in case of accident chemical pollution. The fifth class of models was developed to assess the influence of protection barriers to reduce air pollution Computer codes were developed on the base of proposed numerical models.
