【摘要】 应用液-固两相流理论,利用PHOENICS软件的IPSA解法对环形空间中液-固两相流动的特性进行了数值模拟计算,并用ORIGIN软件对计算数据作了进一步处理,分析了同心环空中液-固两相流紊流的轴向速度分布、固相颗粒沿径向的浓度分布、颗粒直径对滑落速度的影响、固相浓度对滑落速度的影响,得出了一系列关于液-固两相环空流动的规律。更多还原

【Abstract】 A numerical simulation is done to the annular two-phase flow of solid-liquid using liquid-solid two phase flow theory and the IPSA solution of the Phoenics software.Further data processing is done using the Origin software.A series of rules goverening the liquid-solid two-phase annular flow in concentric annulus is revealed by analyzing the radial turbulent flow velocity distribution,radial concentration distribution of solid particles,the effect of particle sizes and solids concentration on slip velocity,providing a theoretical basis for research and analysis of the same flow pattern in industry.更多还原
