Abstract

The objective of the present study is to develop a model to predict heat and gas flow movement by fire in a tunnel. The model includes component models such as turbulence model, combustion model, fire model, jet fan model, etc. It has been validated using the data from Memorial Tunnel Fire Ventilation Test Program. The predictions are in good quantitative agreement with the experimental data in the far-field region of the tunnel. It should be further investigated to develop models for radiation between surfaces, for composite boundary conditions for conduction and convection, and for vigorous turbulent mixing in a tunnel especially for a large size of fire.
