Heat-mass exchange processes dynamics forecasting in fires in typical multistorey apartment buildings

Abstract

Heat-mass exchange dynamics forecasting in fires in typical multistorey buildings allows to prove the need and determine organizational and technical solutions parameters aimed to increasing such buildings residents safe evacuation probability, which is an urgent problem according to statistics on the deceased persons number of this population category as a result of fires. On the numerical studies results basis, the characteristic time changes regularities of critically dangerous fire factors for humans are established; the most dangerous factor according to the people safe evacuation possibility from these buildings is the optical smoke concentration level. A method for determining the critical smoke time for safe evacuation has been proposed. It is proposed to equip mass construction 5–9 storey apartment buildings with early fire detection and warning systems.
