Abstract

With so many bus fires happened in the past years, a series of investigational works were carried out. This paper is on reporting the results on smoke movement by scale modeling technique. A 1/10 scale double-deck bus model was constructed. A pool fire was placed at different positions of the lower deck of the bus model. Smoke spreading from the lower deck to the upper deck was observed. Air temperature profiles in the two decks were measured. Further, performance of two smoke control schemes with natural vents was evaluated. By opening a ceiling vent or the rear window, smoke can be removed. The smoke temperature in the upper deck is reduced.
