A numerical study on smoke behaviors in inclined tunnel fires under natural ventilation

To investigate the effect of tunnel slope on hot gas movement and smoke distribution in a slopping tunnel fire, a series of tunnel fire models are built by fire dynamics simulator (FDS), with a slope varies from 0 to 10%. Parameters such as ceiling temperature and airflow velocity are measured. The...
