Effect comparison of smoke control mode in high-rise building aisle

In order to study the effect of common smoke control model, the numerical simulation combined with the full size experimental have been used to analyze effect of several modes, which composed with the smoke screen, mechanical smoke and air curtain, and the smoke temperature distribution, concentration distribution, and smoke down time between these model is compared. The results show that smoke preventing air curtain and pressurization in atria, with two smoke vents in aisle has the best mode of smoke control effect, which has exhaust efficiency about 74.52% It not only can let smoke out timely, but also can guarantee safe evacuation environment in atria.
