Study on Building Fire and Evacuation Based on Numerical Simulation
In order to study the development law of building fire and evacuation, a university canteen was taken as the research object, and typical fire conditions were set up. Pyrosim and Pathfinder software were used to carry out fire simulation and evacuation research. According to the results of the simulation experiment, the changes of CO concentration, temperature and visibility in the building with time, as well as the evacuation time of the people in the building, can be obtained whether the evacuation time of the people after the fire meets the standard. The results show that the model can effectively simulate building fires. The visibility is lower than the minimum standard for evacuation at 225 s, and the CO concentration and temperature only affect the evacuation after 450 s. Visibility is the most critical factor to determine the available evacuation time. Evacuees should judge the distance and crowding degree of the evacuation exit when choosing the exit.
