Feasibility Analysis for Corridor-Atria Buffer in Smoke Control of High-rise Building

摘要：

In the fires of high-rise building, with the deeply research on pressurization air supply, there still exists some flaws. Corridor-atria buffer is proposed to be set between corridor and atria, which are used to improve the conventional pressurization air supply system. And Fire Dynamic Simulation is applied to simulate the model of high-rise fire. The corridor-atria buffer is simulated in straight corridor, L-shaped corridor and ring-shaped corridor respectively, compared with the temperature field and concentration field, as well as their own smoke efficiency. The results show that the setting of buffer can be applied to the different corridor models, improved conventional one, which not only is easy for people to evacuation, but also increase the efficiency of smoke extraction significantly to ensure that the smoke is let out in corridor timely.
