- •
Reduced experiment on tunnel fire behaviors of asymmetrical sealing was conducted.
- •
Temperature distribution in the tunnel and radiation near the entrance were tested.
- •
Characteristics of fuel burning, smoke flow, hot plume size, etc. were analyzed.
- •
Fire shifts to the side with lower ratio as entrances are sealed asymmetrically.
- •
Ceiling temperature of different sealing ratios along tunnel was compared.
