摘要:
基于非定常数值计算,对大型轴伸贯流泵进行全流道数值模拟,分析叶轮进出口处压力脉动特性,并基于双向流固耦合对叶轮叶片结构进行结构性能分析。结果表明:叶轮进、出口处压力脉动变化幅值均沿径向位置增加而增大,叶轮进口处压力脉动呈周期性变化,而叶轮出口处靠近轮毂位置受动静干涉影响较大;叶轮进、出口处压力脉动主频均为叶频,但叶轮出口处靠近轮毂位置次频影响较大;叶轮叶片轮缘处最容易发生形变,应力集中于叶片叶根附近,最大形变位置集中在叶片进水侧轮缘处。
Abstract:
Based on the unsteady numerical calculation, the full channel numerical simulation of the large tubular pump was carried out to analyze the pressure pulsation characteristics at the inlet and outlet of the impeller, and the structural performance of the impeller blade structure was analyzed based on the two-way fluid-structure coupling. The results show that the pressure pulsation amplitudes at the inlet and outlet of the impeller increase along the radial position. The pressure pulsation at the inlet of the impeller changes periodically, and the position near the hub of the impeller outlet is greatly affected by the dynamic and static interference. The main frequency of the pressure pulsation at the inlet and outlet of the impeller is blade frequency, but the sub-frequency at the outlet of the impeller near the hub has a great influence. Deformation is most likely to occur at the edge of the impeller blade, the stress is concentrated near the root of the blade, and the maximum deformation is concentrated at the inlet edge of the blade.
