A study of smog diffusion when a fire takes place in tunnels

철도 터널 단면적에 따른 연기 전파 연구

We studied three dimension numerical analysis in the case that a train stops in tunnels by fire. And the 'Fluent 6.1' which is CFD(Computational Fluid Dynamics) program was used in this study. We compare the smog diffusion in single/double track ordinary railway tunnels with that in double track high speed railway tunnels in this study.
