“…A nonsteady energy balance for the "closed" compartment can be expressed as a simple differential equation. (3) where the mass of the fuel is ignored, the energy lost through leakage is ignored, and the initial temperature is equal to the ambient temperature. ilT is expressed as the temperature above this datum.…”

“…Relatively few forced ventilation compartment fire experiments have been performed. Of the forced ventilation compartment fire experiments, the earlier work focused on forced ventilation provided at the base of the compartment [3,4]. Only relatively recently have overhead forced ventilation compartment fires been studied experimentally [5,6].…”

Compartment fire data with either no ventilation or forced overhead ventilation are successfully modeled as well-stirred fire environments rather than two-layer fire environments, The extinction of flames is predicted using the limiting oxygen index concept linked with a well-stirred model of the fire environment. While the fire environment in compartments with overhead ventilation is quite different than naturally-ventilated fires or fires ventilated from floor level, a temperature model previously developed by Beyler and Deal is shown to predict preflashover temperatures in forced ventilation fires.

Experimental studies on the temperature distribution in forcedventilation fires at preflashover stage were conducted in a small test chamber with ethanol pool fires. A total number of twenty-eight tests divided into four cases of ventilation conditions were performed. The effect of ventilation rate, ventilation positions and the size of the pool fire on the heat release rate, temperature rise, height of hot layer and heat flux on the wall surface were studied. The rate of heat release was determined by the methods of mass loss rate and oxygen consumption. With the calculated heat release rate, the experimental results on the smoke temperature rise were compared with the results predicted by using the energy balance equation as recommended by Deal and Beyler and the correlation relations derived by Foote, Pagni and Alvares. It is found that the equation proposed by Foote, Pagni and Alvares gave a reasonable prediction on the temperature for this set of experiments.

Force-ventilation compartments are a common environment for fire growth in sealed or high-rise structures. Currently, no method exists for reliably estimating the fire hazard in these enclosures. Using data from compartment fires in the forced ventilation facility at the Lawrence Livermore National Laboratory (LLNL), a simple correlation has been developed following the methods of McCaffrey, Quintiere and Harkleroad. The upper layer temperature rise above ambient, LIT = Tu -Too, is given as a function of: the fire heat release rate, G, the compartment mass ventilation rate, m, the gas specific heat capacity, cp,
