摘　　要：为了探明多层住宅烟道串味的机理,采用κ-ε湍流模型,利用两相流理论,对多层住宅烟道内的流场进行数值模拟,得到烟道内的压强、速度和体积分数分布图.结果表明:在第一支烟道与主烟道的交汇处压强梯度较大,一楼排放的烟气大部分向上流动,第二支烟道附近油烟的体积分数梯度大.To find the mechanism of refluence in the flue, authors conduct the numerical simulation of liquid-field in the flue of multilayer building by adopting κ-ε turbulent flow model and two-phase flow theory, and plots the charts that the pressure, consistency and velocity distribute in the flue. The result demonstrated that the pressure grads is larger at the meeting of the first flue and main-flue, the most gasoil of the first floor flows up, and the gas-oil consistency grads is larger nearby in the second flue.
