Abstract

In this paper, large-scale fire dynamics simulator (FDS) model software was used to simulate a cinema fire. The reliability of the simulation results was verified by comparison with relevant research results and some fire precaution measures were put forward. Based on the physical fire model of 1:1, full-scale simulation of a cinema fire was carried out. By studying the flue gas, temperature and variation law of the CO concentration during the fire, it is found that the mechanical air-intake damages the stratification of smoke and air in the burning room to a certain extent. The lower air in the theatre is mixed with the upper high-temperature flue gas so that the temperature of lower air is higher than that of upper air. Meanwhile, the mechanical air-intake enhances the reducing speed of visibility. The results of this research provide a reference for the fire protection design of cinemas.
