...Kexin Pu; Xiangsong Liu; Qipeng Li; Shangxiang Lu; Bin Huang; Dazhuan Wu The physical mechanism, evolution process, and control method on pulsation caused by flow-induced excitation vortex in an axial flow pump are elaborated by numerical calculation and experiment. The mechanism formulation...

... also presented in this paper to verify the effects of modified impellers on pressure pulsations. Since the pressure pulsation at f BPF is an important index to measure the strength of internal flow-induce excitation in centrifugal pump, Fig. 13 presents the amplitudes at f BPF versus with flow...
