摘要

为了研究大型灯泡贯流泵的能量损失特性

采用基于有限体积法的数值模拟

结合局部熵产率和网格尺度

通过熵产理论定位贯流泵内能量损失较高的局部区域

分析了不同工况下各部件内局部熵产、能量损失和不稳定流动之间的关联。结果表明:贯流泵系统熵产与试验功率损失保持较高的一致性

相比于大流量工况

小流量液流正冲角更容易诱导能量损失; 叶轮轮缘局部熵产最高

体积占比14%的轮缘子域耗散熵产占比超过40%

由叶顶区泄漏流和泄漏涡导致; 导叶轮毂和轮缘侧耗散熵产较高

且呈现轮毂侧分散、区域大极值小

轮缘侧集中、区域小极值大的分布特性; 灯泡体能量损失在小流量工况下集中在尾部渐缩段

在大流量工况下集中在灯泡尾部的尾迹区。该研究成果对大型泵站群水力性能优化设计及高效、稳定运行具有参考价值。

Abstract

To study the characteristics of energy loss in large-scale bulb tubular pump

numerical simulation based on the finite volume method is used to analyze the correlation among the local entropy generation

energy losses and unsteady flow of each component in different working conditions by combining the local entropy generation rate and mesh size and by locating the local regions with high energy loss within the tubular pump with the entropy generation theory. The results show that the calculated entropy generation of the bulb tubular pump is highly consistent with the measured energy loss

and flow instability and energy loss are more easily to be caused at positive incidence angle at lower flow rates. Local entropy generation peaks near the shroud of the impeller that more than 40% dissipative entropy generation is caused by the sub-region occupying roughly 14% of the total volume

which can be attributed to the leakage flow and leakage vortex in the blade tip region. The dissipative entropy generation in the region of guide vane reaches relatively high value at both hub and shroud side

showing the characteristics of large volume and low level at the hub side but small volume and high level at the shroud side. The energy loss in the bulb concentrates on the tapered tail at low flow rates and shifts to the wake area behind the bulb tail at large flow rates. The research results provide reference for the hydraulic performance optimization and high-efficiency and high-stability operation of large-scale pumping stations.
