Heat effects on external designs at a fire
The analysis of fires at which the flame extends on external designs of facades is carried out. Features of the mechanism of such flame spreading are considered. The calculation method of heat effects on the external designs which allows defining: the maximum temperature in the fire compartment (section); sizes and temperature of a flame from apertures; parameters of radiation and convection. The example of simulation of the indoor fire development and its distributions after opening of a window aperture on the facade is presented. Efficiency of application of vertical crosscuts and horizontal canopies over the entrances with a view to reduce the risk of the flame spreading on facades is considered.
