“…All the fluctuations have a low-frequency component of about 0.27 f n , and the pressure coefficients at different positions fluctuate synchronously. Similar study was firstly carried out in the previous work of this research, 31 which mainly presents the backflow phenomena near impeller inlet and its effect to the cavity volume and inlet flow rate. In this paper, the main results and conclusions are reviewed and further summarized to show the instability under the condition when the mass flow gain factor of Pump B is positive.…”

“…There were no flow rate oscillation or low-frequency pressure pulsation in Pump A but only some pressure pulsations related to the impeller rotating and blades passing. However, for Pump B, results show obvious low- 31 which mainly presents the backflow phenomena near impeller inlet and its effect to the cavity volume and inlet flow rate. In this paper, the main results and conclusions are reviewed and further summarized to show the instability under the condition when the mass flow gain factor of Pump B is positive.…”

“…The end of this section highlights the fact that the tip clearance recirculation plays significant role to the performance of the pump and the possible development of cavitating formations (Tani, 2012;Kang, 2019). For this reason the effect of its thickness is examined in the next section 5.2.1.1.…”
