説明

Most studies on mathematical simulation for enclosure fires have been conducted by using energy and mass balanse equations. The terms of generation and consumption of heat or mass in these equations determines the worth of the models. Especially, that of heat generation in an enclosure seems to be troublesome to formulate. It was indicated that the dependence of heat capacities and chemical equilibrium compositions on temperature have great influences on the evaluation of heat generation in an enclosure. Reaction efficiency, which is related to the degree of mixing of fuel and entrained air, have also great effects on this evaluation. In this paper, the variances of gas temperature in fire were calculated by using the estimated degree of mixing. And the effects of heat capacities of chemical shemical species and mixing of fuel and entrained air on the evaluation of heat generation in an enclosure were discussed.
