MODELING OF TEMPERATURE IN THE ROOM AT PRESENCE OF THE OPEN FLAME IN CONDITIONS OF FREE CONVECTION

The non-stationary task of definition of a temperature field in a room in an initial stage of a fire is considered in view of the basic thermal and physical parameters in conditions of free convection. The assumption has been made, that the model of movement of air is one-dimensional and free convention is provided with natural ventilation by use aeration lanterns. Efficiency of the received decision has been checked up on the experimental installation representing the reduced breadboard model of a real room. The opportunity of forecasting of time of achievement of critical value of temperature in a room in an initial stage of a fire by a method of graphic construction of the current and critical values of temperature is shown.
