WebFeb 1, 2002 · All computer models for post-flashover fires are based on heat balance. Fig. 2 shows the main components of heat flow in a simple compartment fire. The heat produced by combustion of the fuel q ̇ c is balanced by the heat losses; the main components being heat conducted into the surrounding structure q ̇ w, heat radiated through the opening q ̇ … Webbetime to flashover is normally taken from the time ofignition. Hence the longer the time to flashover, le more opportunity there is for detection and suppression ofthe fire to occur, and for the occupants to vacuate safely. The time to flashover therefore has an important impact on the safety ofoccupants and lelikelihood ofextensive damage to property [1].]. Although …
