Simulation of fire smoke spread in small and medium-sized restaurants
Taking a small and medium-sized restaurant as the research subject,PyroSim fire simulation technology and the or-thogonal test method were used to design the simulation conditions.The fire process under different window areas and fire source power with natural ventilation was studied by combining qualitative analysis and dynamic simulation.The spreading law of fire smoke was analyzed from different angles such as temperature,visibility,and CO concentration.The results show that,with the same fire source power,the larger the window opening area is,the smoke volume can be reduced significantly,the diffusion of smoke can be delayed,and the safety evacuation of personnel can be facilitated.When the power of the fire source is different,the law of smoke spread and diffusion is roughly the same,the temperature and CO concentration increase with the power,while the visibility decreases.
