摘要
在三角形迷宫螺旋泵理论分析基础上,运用商用计算软件FLUENT,采用雷诺时均N-S方程和标准k-ε湍流模型,运用基于非结构网格的SIMPLEC算法,对清水状态下三角形迷宫螺旋泵内三维湍流场进行了数值模拟,从而得到了螺旋泵内部流动的主要特征和外特性变化规律.根据试验结果得出泵的外特性曲线,并与数值模拟计算的结果进行比较,发现两者的外特性规律非常一致,这说明所采用的计算模型基本符合泵内部流动的实际情况.研究结果可用来了解三角形迷宫螺旋泵的内部流场特征,为螺旋泵的设计、改进和优化提供有益的参考.
Based on the theoretical analysis of a triangular labyrinth screw pump, the 3D flow of clean water inside the pump was simulated with the software FLUENT. The Reynolds time-averaged N -S equation, stand k -ε turbulent model and SIMPLEC algorithm based on unstructured mesh were adopted. The diversification of the main characters of inner flow and the outer characters were obtained. By comparing the results from test and simlation, it is discovered that both performance rules are very consistent, which proves the validity of the calculation model. The results can be used to explain the interior flow field characteristics of the triangular labyrinth screw pump, and will provide some useful references for its design, improvement and optimization.
