Simulation Study on the Impact of Obstacles on Fire Explosion Characteristics in Stadium

Abstract

As large-scale public buildings,sports stadiums are extremely dangerous in case of fire due to their special structural layout and high density of people. This paper focuses on the influence of obstacles within sports stadiums on the deflagration characteristics of fire, aiming to provide a theoretical basis for fire prevention and control and safety design. Through establishing the geometric model of sports stadiums and combining with numerical simulation, the influence of the existence of obstacles on flame propagation is analyzed. The research results indicate that obstacles can aggravate the deflagration characteristics of fire to a certain extent, especially when obstacles are dense or the space is limited, the flame propagation path is obstructed, leading to a sharp increase in pressure. The research in this paper has significant reference value for optimizing the fire protection design of sports stadiums. It is recommended that the arrangement of obstacles and their potential influence on fire risks be considered at the architectural design stage.
