摘要
Abstract
The theoretical calculation method of exhaust velocity and the critical thickness of smoke layering under exhaust damper when plugholing occur in a horizontal highway tunnel under 30 MW fire were analyzed. The temperature, velocity and the smoke layering thickness under exhaust damper were obtained by numerical simulation. The phenomenon of smoke layering plugholing under exhaust damper with different exhaust velocities was confirmed, which would offer reference for the optimization of central smoke extraction model.关键词
