Numerical Study of the Effect of Different Transverse Fire Locations on Smoke Mass Flow Rate in Tunnel Fires

Wall restriction is an important factor affecting flame space development, air entrainment and heat transfer. To investigate the smoke characteristics in the one-dimensional horizontal spreading stage at different transverse fire locations in tunnel, FDS was used to simulate and analyze the smoke ma...
