With the rapid development of economy, the number of buses and bus fire increases. This paper takes bus as the research object and uses software FDS to explore the fire smoke spread under different fire power conditions. The results show that: with the increase in fire power, the smoke in the compartment rapidly accumulates, and the heating rate is also accelerated. The visibility decreases with the diffusion of smoke in the compartment. The CO concentration increases with time. The greater the fire power, the higher the temperature which will eventually stabilize. Only the concentration of smoke near the entrance will be slightly reduced. This is also conducive to the escape of people inside the car.

Smoke Spread

Fires in high-rise residential building were studied experimentally by using an actual building with similar inner structure. The temperatures in the building interior corridors, elevators and staircases exit were measured. At the same time the fires in this construction were simulated by using FDS (Fire Dynamics Simulator) software, the variance trends of the temperatures in different positions within high-rise residential building were studied and compared with the experiment results, and the results of this simulation are proved to be valid. The results can be used to support the study of effectively controlling of the smoke spread and evacuation in high-rise residential building.
