Influence factors and prediction model of enstrophy dissipation from the tip leakage vortex in a multiphase pump

open access: yesScientific Reports, 2022
In a multiphase pump, tip clearance is the required distance between the blade tip and the pump body wall of the impeller, forming tip leakage vortex (TLV), causing unstable flow and energy dissipation.
