【摘要】 固液两相流运动特性是水动力学中的一个研究热点。本文建立的三维k--εAp两相湍流模型首先研究了模型中颗粒相的两个控制参数对数值结果的影响,然后讨论了不同的颗粒平均粒径、水流流速与颗粒材料密度等三种情况下固液两相流的时均运动特性。数值计算结果和试验实测结果吻合良好。更多还原

【Abstract】 The movement characters of liquid-particle flows are of great importance in hydrodynamics.Analyzing and specifying two parameters in the control equations of particle phase,the authors investigated numerically the time-averaged movement characters of liquid-particle flows with different diameters of particle,different flows and different densities of particle by applying threedimensional k-ε-A_p model.The numerical results are in good agreement with experimental ones.更多还原
