MODELING OF TEMPERATURE IN FIRE REGIMES WITH A VIEW OF THE WORK OF EMERGENCY VENTILATION IN PERMEABLE ENVIRONMENT

Determination of the calculated values of the risk of fire in buildings and constructions allows quantitatively characterizing the possibility of realization of potential fire danger in the fire and assessing its possible consequences. In the analysis of the risk of fire is considered as the possible number of deaths and injured during a fire people, the destruction of the spiritual and material values, environmental damage, and the probability of failure of the automatic installations of fire alarms and fire fighting and many other factors affecting the development of the fire and its consequences. One of the major parameters that affect the value of fire risk is of the time of the critical values of the dangerous factors of a fire. The problem of modeling the average temperature in the room in case of fire. Modeling of physical and chemical processes of the initial stage of fire requires the analysis of the parameters describing this process. The correct choice of the most significant parameters to build adequate model. Defined parameters, influencing the dynamics of the development of a fire. Methods of the theory of dimension of similarity and allowed to get the criterion equation. On the basis of this equation obtained the relation that binds temperature and the main parameters of the combustion process. Analysis of the impact of exhaust emergency ventilation has shown that its performance can be attributed to the general settings. Conclusion. With the help of the method of the matrix obtained by the calculation formula, which allows to analytically describe the dynamics of change in the average temperature of the gas environment in the room in the event of fire in the conditions of work exhaust emergency ventilation.
