摘　　要：进行管汇水动力分析和计算,确定准确的管汇受力数学模型对于管汇的下放系统数值分析以及安全下放安装具有重要意义。通过流体动力学软件FULENT建立管汇的水动力计算模型,求得管汇非惯性水动力系数,数值结果与现有的经验估算结果进行比较和分析,验证了该方法的有效性,为管汇下放安装的仿真和控制奠定了基础。Hydrodynamic analysis and calculation have to be carried out on the manifold to deter- mine the accurate mathematical model of forces acting on the manifold. It is of great significance for the numerical analysis of manifold lifting system and safety installation. Manifold hydrody- namic calculation model was set up based on CFD software FULENT, manifold hydrodynamic drag coefficients was obtained, the results of numerical calculation was compared with existing empirical estimates verifying the effectiveness of the method. This method laid the foundation for simulation and control of the manifold installation.
