Influence of draft curtain height on smoke exhaust effect in a large area metro depot
نویسندگان
چکیده
The metro depot area has the characteristics of large and high storey smoke diffusion under fire conditions in these areas are more complicated. It is important to investigated exhaust effect which closely related safety firefighters. FDS (Fire Dynamics Simulator) numerical simulation method was adopted investigate influence draft curtain height on performance fan were installed inside wall area. heigh set as 0.5m,1.0m,1.5m,2.0m,2.5m,3.0m respectively. propagation smoke, concentration CO 2 at outlet efficiency analyzed. For vents side wall, would have greatly efficiency. As increases, spread distance horizontal direction becomes short.it beneficial improve wall. research results could provide references for protection design subway

15 صفحه اولExperimental investigation on influence of smoke venting velocity and vent height on mechanical smoke exhaust efficiency.
A set of burning experiments were conducted to investigate the influence of smoke vent height and exhausting velocity on mechanical smoke exhausting efficiency. Results have shown that the smoke exhausting process becomes more efficient due to the increased smoke vent height and the decreased exhausting velocity, which eliminate the plug-holing issue with fewer disturbances on the smoke layer i...

since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
