电梯运动对电梯井及其前室烟气运动影响的数值模拟

In this article, the factors of smoke movement in high-rise building elevator shaft are analyzed, the physical model of a elevator shaft is established, a CFD tool is used and the large eddy simulation is used to do the numerical simulation and study the smoke movement in the elevator shaft and elevator room under different operating conditions. The results showed that: the pressure distribution of the elevator shaft is more disorder when the elevator is running, smoke is easier to enter the elevator room through the crack, and the percentage of CO is higher than the other situation. Therefore, in addition to the air supply in the elevator room, the crack area should be minimized and a more reasonable way of air supply is used in elevator shaft.
