Abstract

Ivan Kerchief, Oleg Mirochnik, Larysa Pereverzieva APPLICATION OF FIELD THEORY APPARATUS FOR DESCRIPTION OF AIR MOVEMENT IN MATHEMATICAL MODEL OF PREVENTION OF EMERGENCY SITUATIONS OF TECHNOGENIC CHARACTERISTIC CHARACTER The main provisions of the field theory for the description of air movement processes in the closed premises of administrative buildings in the conditions of emergence of an emergency situation of technogenic character are defined in the work. Based on which the main assumptions are made regarding the problem of mathematical description of the process of air injection into the local volume using a filter ventilation unit in the interests of protecting people from the damaging factors of radioactive and chemical contamination in enclosed office buildings in a man-made emergency. A detailed analysis of the existing regulatory and methodological framework on the issues under consideration allowed us to state the following - known means of protection against radioactive and chemical contamination of the atmosphere are implemented in special protective structures, which are in large numbers in Ukraine, but for objective reasons (obsolete physically and morally) can not be used for its intended purpose. Existing methods of building temporary shelters cannot be implemented due to the rapid development of emergencies at present. Therefore, it is necessary to develop and propose new designs of special rooms in office buildings in the interests of protection and rescue of people from the harmful factors of hazardous substances sprayed into the atmosphere as a result of man-made disasters, which in turn should be based on modern methodological apparatus. closed premises of administrative buildings in the conditions of emergence of an emergency of technogenic character. Given the above, the properties of the vector function used to describe magnetic and other physical fields that do not contradict the provisions of gas dynamics and can be used to describe the problems of air injection in the local volume were considered. It is noted that the direction and modulus of the vector determine the direction and velocity of the air flow through the elementary site. In addition, the vector function allows you to represent (conditionally divide) the air flow as elements of lines or elements of surfaces. Thus, the properties of the vector function allow to use it to describe the processes of air injection into the local volume in the mathematical model of protection of people from the damaging factors of radioactive and chemical pollution in temporary shelters in office buildings in order to protect the population from the damaging factors of radioactive and chemical pollution. arising from man-made accidents and catastrophes. Key words: emergency situation, field theory, administrative buildings.
