Analysis of Smoke Hazard in Train Compartment Fire Accidents Base on FDS

Train compartment is very special confined spaces; fire smoke in compartment brings great hazards when fire broke out. It is the main reason which caused people to die or hurt. This paper uses CFD method based on the FDS. It analyzes the main features of fire smoke on the human body injury; simulate smoke flow caused by compartment fire; It computes and analyses the interior fire smoke's diffusion process, the cabin space area of smoke concentration distribution and the temperature distribution and trends, and discusses and analyses the impact of smoke and temperature change in the train personnel in emergency evacuation.
