Research on the influence of door opening situation
on fire spread in residential fires

Abstract

Abstract: Through the numerical simulation and full-scale experiment of typical residential building fires, the fire development trend in the living room and the temperature, visibility and CO concentration distribution in the bedroom under different opening conditions of the doors and the windows were studied, and the impact on the escape of personnel was analyzed. The results show that the spread and accumulation of smoke is an important factor that jeopardizes the safety of personnels. When the living room is on fire, saving the fire within 680 s is the best choise. In addition, closing the bedroom door and opening the bedroom window can increase 497 s of the emergency response time.

Key words: residential fire, visibility, temperature field, numerical simulation
