During high-speed rotation, centrifugal forces are greater that the capillary forces restricting the fluid from overcoming the siphon crest. But when speeds are lowered to a critical speed, the capillary forces overcome the centrifugal force and actuate the fluid through the valve and toward the ...
Wei and Wang [11] studied the unsteady hydrodynamics of blade forces of a submarine propeller based on the URANS method. There are also former research works that focused on the suppression of pressure fluctuation and vibration by modifying the geometry of pump parts. Wu and Yan [12] presented...
