Small-scale fire tests in the underwater tunnel section model with new sidewall smoke extraction
• A 30:1 underwater immersed tunnel model was built and 140 sets of fire model experiments were conducted to reproduce various scenarios of tunnel fires. • The diffusion law of smoke was studied. Without ventilation, smoke is effectively blocked by the smoke exhaust cross section and controlled within 2–3 smoke prevention intervals. • The aims of this work are to study the smoke exhaust effect, compare the smoke exhaust effects of different ventilation air volumes and fan operation modes, and summarize the best smoke exhaust plan.
