CFD STUDY OF TEMPERATURE AND SMOKE DISTRIBUTION IN A RAILWAY TUNNEL

A study of safety in a railway tunnel with natural ventilation system is presented. The study investigates conditions within the tunnel near a burning train. An emergency scenario is defined and criteria for the assessment of the safety of the escaping passengers are discussed. Two different approaches were employed in a coupled manner: 1-D analysis using the code SPRINT, developed by HBI, and 3-D CFD analysis using the commercial code FLUENT It is concluded that the 1-D approach is, in most cases, sufficient for an overall safety assessment, whereas 3-D CFD is more appropriate for gaining additional insight in regions of particular interest in complex tunnel geometry.
