Analysis on Influence of Rotational Speed on Solid-liquid Flow Velocity Vector Distribution in Slurry Pump

  • 摘要: 为了研究转速对深海采矿矿浆泵内部流动特性及对工作性能的影响,应用欧拉模型,RNG κ-ε(Renormalization-group κ-ε)湍流模型及SIMPLEC算法,对矿浆泵叶轮及空间导叶内固液两相流场进行数值模拟,研究叶轮叶片和导叶叶片的绝对速度分布及外特性的影响。结果表明:随着转速n的增大,叶轮流道区域内的边界层更易分离,过流能力减弱,在叶轮出口处,射流-尾迹结构越强,水力损失越严重。空间导叶流道进口处的冲击更加猛烈,此区域流动愈加混乱,在导叶压力面进口处出现了范围更大的二次流。但随着转速n的增大,混合流体在导叶吸力面进口处的流动分离被抑制了,增大了过流能力,减弱了水力损失。
