原始语种摘要: Abstract(#br)An experimental study on smoke filling in closed compartments with elevated fire sources is presented. Experiments were conducted with elevated fires in a closed compartment with interior dimensions of 3.000m ( L )×3.000m ( W )×1.950m ( H ). Various parameters, such as the light extinction coefficient, the oxygen concentration and the gas temperature, showed distinct stratification phenomena, and the interface of the stratification was the fuel surface level. The results indicated that the smoke layer descended to the fuel surface level but did not descend directly to the floor at the center of the compartment; rather, it continued the filling process by wall jets. A similar stratification was observed in a closed...
