... is considered to be a forced vortex, while the outer region is considered to be a free vortex. The ratio (f) of the forced vortex to the distance between the backflow-vortex center and the casing is defined. Each backflow vortex has a circulation and induces movements of all the other backflow vortices...

...Baofeng Yang; Bin Li; Hui Chen; Zhanyi Liu; Kaifu Xu The clocking positions between the inducer and the impeller have a certain impact on the performance of the high-speed centrifugal pump, which however, is often ignored by designers. In the present study, three-dimensional numerical simulation...

... effects on suction performance in this cavitating inducer pump. These three test cases exhibit equal suction performance at three different values of the dimensional thermal effects parameter Σ . This was achieved by varying the pump operating speed as required to maintain a constant DB value. Thus...

...Wen-Guang Li In the inducer hydraulic design, one significantly important task is to estimate its noncavtating head; however, there is not a matured and reliable method for this presently. In this paper, a method was made for predicting the inducer head curve. The method was based on a singularity...

...Nobuhiro Yamanishi; Shinji Fukao; Xiangyu Qiao; Chisachi Kato; Yoshinobu Tsujimoto Turbopump inducers often have swirling backflow under a wide range of flow rates because they are designed with a certain angle of attack even at the design point in order to attain high cavitation performance. When...

...Young-Do Choi; Junichi Kurokawa; Hiroshi Imamura Cavitation is a serious problem in the development of high-speed turbopumps, and an inducer is often used to avoid cavitation in the main impeller. Thus, the inducer often operates under the worst conditions of cavitation. If it could be possible...
