Numerical simulation study on bus fire

With the development of urbanization, more and more buses come into people´s lives, and a lot of bus fires have occurred to personnel and properties in occupied areas. So this paper aimed at the typical bus fires, through setting different fire scenarios, dynamic process of bus fires was studied by using FDS, and the effects of combustible material type, fire source location and ventilation on smoke spread, temperature and heat release rate were discussed. The results could provide some information for risk assessment and prevention of bus fire.
