| 1 | 离心式水力空化发生器空化空蚀机制试验研究显示文摘该文对一台转子-定子型离心式水力空化发生器的性能进行了系统的试验研究,以寻求其空化生成机制并与空蚀分布之间的关系。可视化试验结果表明空化发生器内存在楔形槽空化、转子叶齿和定子叶齿前缘空化。通过水听器测量了空化发生器蜗壳侧面位置的压力脉动情况,在相同转速下压力脉动随着流量的增加而增大,压力脉动周期不变;在相同流量下压力脉动随着转速的增加而增大,周期减小:50 Hz时压力幅值为30 Hz时的2.5倍,周期缩短0.001 s。油墨法试验结果显示空蚀主要发生在转子叶齿尾端和中部,定子叶齿前缘空泡附着部分及尾端。楔形槽空化是造成破坏的主要原因,因其空化强度最高且空泡溃灭行为离固壁表面最近。该研究可为离心式空化发生器的研发提供参考。 | 王健 刘厚林 Matevz Dular | 2017 | 农业工程学报2017，33，14： | 4 |
| 2 | 转子—定子型离心式水力空化发生器非定常空化形成机制显示文摘为了研究一种高效水力空化发生器的运行原理,采用试验测试与数值模拟结合的方法研究了一台转子—定子型离心式水力空化发生器内的非定常空化机制。数值计算与试验吻合较好,结果表明空化发生器内存在三种空化机制:钝头体绕流空化、尾涡空化和楔形槽空化,分别位于转子叶齿前缘、叶齿后侧和定子叶齿前缘,其中定子叶齿前缘空化具有明显的周期性。空泡整体分布不完全对称,定子叶齿前缘空化主要发生在蜗壳5-8断面间;转子叶齿前缘空化发生在8-1断面间,而后侧尾涡空化变化幅度较小。空泡体积含量呈周期性变化,与一对转子—定子叶齿的交错周期相吻合。研究成果可为离心式水力空化发生器的优化设计提供参考。 | 王勇 严骏 王健 刘厚林 Matevz Dular | 2018 | 哈尔滨工程大学学报2018，39，12： | 4 |
