With the exploitation of deep sea and desert oil fields, multiphase pumps have come into the public eye. However, due to the nature of the medium and operating environment, the performance of traditional multiphase pumps has diminished, leading to pr

Tip clearance inevitably exists in helico-axial flow multiphase pumps, which generates a great impact on flow characteristics. To select a reasonable tip clearance and improve the transporting efficiency, different tip clearances (Rtc = 0.5, 1.0, and
