【摘要】 对新型净水装置—浑水水力分离清水装置内部清水流场进行三维数值模拟。应用雷诺应力模型建立数学模型,采用有限体积法离散方程,运用SIMPLEC算法进行求解,初步得到浑水水力分离清水装置清水流场的分布规律。经分析发现,该装置内的流动是典型的三维非轴对称流场,其中的切向流速分布呈现出明显的强迫涡特征,其垂直面上,形成一内侧向下、外侧向上的环形流动。同时,通过与试验结果进行对比,证明利用雷诺应力模型可以有效模拟装置内的清水流场。更多还原

【Abstract】 Using the three-dimensional numerical simulation to compute the field of clear water of turbid water hydraulic power separation equipment in this paper.The SIMPLE algorithm are used for solving standard RSM model discreted with finite volume method.On the basis analysis,the separator of flow is a typical 3D non-axial symmetry flow field,tangential velocity show the force vortex characteristic.On the vertical surface of separator,revolved flow is upward outside of the separator and downwards inside of the separator.更多还原
