abstract

Building fires have been paid significant attention in the nuclear power station’s safety. In order to study the stratification phenomena of the enclosure fires and predict the interface location of upper hot layer filled with smoke and lower cold layer filled with fresh air and upper layer temperature of enclosure fires, an advanced new model is used in this paper, in which one–dimensional differential equations are used to describe the temperature and species distributions of the ambient fluid. And the results of Steckler’s fire experiments are used to compare with the simulation results of five sets of experiment using the new model. The results indicate that this model gives a very good prediction for the location of the interface and the upper layer temperature, especially for the cases with a lower fire heat release rate, even without considering the radiation heat transfer.
