| 摘 要： | 运用气相ｋ－ε湍流模型和颗粒相代数方程模型对正交射流（垂直的交叉射流）尾迹气固两相流动进行了数值模拟，获得了该流动尾迹的气、固相速度分布，颗粒质量流分布，计算结果与实验值定性符合．文中探讨了一次风口（主流入口）粉气质量比对颗粒混合的影响以及颗粒对气相流场的影响，并得到了一些有价值的结论．

| Abstract: | The k-ε two-equation turbulent model of gas-phase and an algebraic formula modelof particle phase are used for the numerical simulation on a gas particulate phase of the trailin an orthogonal jet. The velocity distribution of gas phase and particle phase and the particleconcentration are obtained and compared with the experimental data. The computationalresults are in qualitative agreement with the experimental values. The influence of particleon flow of gas-phase is also presented. |
