Modelling of hazardous chemical gas building ingress and consequence analysis during a leak accident

Abstract: Leakage of hazardous chemical gases during storage or transport via roadways is a common type of accident that threatens human life. This study built a typical residential building model in rural areas of southern China based on Building Information Model technology. The model was then simplified and employed as a target building to simulate the hazardous gas dispersion around it after a leak accident by means of Computational Fluid Dynamic methods. A dose-response model was combined with a probit function ana… Show more

“…This study not only demonstrates the feasibility of these methods but also proposes a more novel approach to predict the diffusion concentration of hydrogen sulfide leaks in real-time. Despite the innovative nature of the methods used in this study, there are some shortcomings (1) for the applicability of the model. Although the model can be extended to other cases of heavy gas leakage, it is only applicable to point source leakage of the gas in a particular scenario.…”
