    Abstract
  • By using three-dimensional design method based on circulation and computational fluid dynamics, the effects of blade number, blade circulation center position and blade trailing edge circulation on rotor performances were studied, the influences of leading edge circulation and trailing edge circulation of stator on axial waterjet pump performances were analyzed, and an axial waterjet pump with high efficiency and good cavitation capacity was designed by controlling the factors properly.When the flow is 56.2m3·s-1, the head, power and efficiency of the pump are 35.9m, 21 465 kW and 92.3%, respectively, so the properties and efficiency of the pump are high.Analysis result shows that increasing blade number is effective to decrease single blade torque, when blade number increases from 5to 7, single blade torque decreases by 21%.Circulation center moving closer to trailing edge is beneficial to better cavitation performance of rotor, when circulation center moves from 3/10 to 7/10 of blade string length, cavitation area on rotor suction side decreases by 80%.The slope of rotor trailing edge circulation affects rotor efficiency, when the slope changes from 0.8to 1.2, rotor efficiency increases gradually.Rotorhead and rotor power almost increase linearly when trailing edge circulation ranges from 0.4to0.5, rotor head increases by 19.9%, and rotor power increases by 19.5%.Pump efficiency firstly increases and then decreases with the ratio increase of stator leading edge circulation to rotor trailing edge circulation, and the efficiency is highest when the ratio is 0.93.Stator trailing edge circulation has effects on pump efficiency, outlet non-uniformity and outlet circumfluent energy, when stator trailing edge circulation is-0.05, pump efficiency is highest, and outlet non-uniformity and outlet circumfluent energy are least.
