Simulation Analysis of the Pressure and Temperature in the Firing Bus

Abstract

Fire accident in the running bus is very dangerous for the passengers. The temperature, pressure, and toxic fumes from the fire accident are the main factors of casualties of passenger in the closed bus. It is necessary to research the factors such as the temperature, pressure and smoke of the fire so as to improve the capability of rescuing the passengers and the passengers self-protecting under the emergency fire disaster. In this paper, the software named FDS is used to model and simulate the process of bus-firing, which a simulation describing the bus catching fire. The height of smog layer, distributions of indoor temperature and the carbon monoxide concentration from the firing bus are analyzed. By means of the simulation analysis of the bus fire procedure, the law of smog movement in the carriage is analyzed, and it is helpful for us to response to similar fire accidents.
