As a compound channel is characterized by a deep main channel flanked by relatively shallow floodplains,the interaction between the faster fluid velocity in the main channel and the slower moving flow...
旋流自吸泵内部湍流场大涡模拟（Large Eddy Simulation on Interior Flow Field of Rotational Flow Self-priming Pump）
旋流自吸泵 大涡模拟 性能预测
2009/9/25
旋流自吸泵蜗壳结构不同于普通泵，具有特殊的流场结构。采用大涡模拟方法和滑移网格技术，通过对设计工况下旋流自吸泵三维非定常湍流场的数值计算，捕捉到泵叶轮和蜗壳内的压力分布、速度分布和尾迹区内旋涡的结构与演化特征等重要流动信息，结果表明叶轮内部静压具有一定的非对称性。分析了分离室内漩涡形成的原因。对含气率分布的分析表明，叶轮中气相主要集中于叶片的吸力面区域。对旋流自吸泵的性能进行预测，得到了预测性能曲...
