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。 The kinetic characteristics of solid-liquid two-phase flow is a hot topic in hydrodynamics. The three - dimensional k - εAp two - phase turbulence model established in this paper first studies the influence of two control parameters of the particle phase on the numerical results, and then discusses the different particle average particle size, water flow velocity and particle material density Under the two-phase solid-liquid flow when the average movement characteristics. The numerical results are in good agreement with the experimental results.
