Hydrodynamic Performance Analysis of the Bionic Impeller Equipped with Little Angle Arc Lamina

This paper mainly imagined and designed a bionic impeller with arc shape lamina especially little arc lamina, researched on its hydrodynamic performance on the base of the prior hydrodynamic performance research on straight panel shape lamina. Applied FLUENT software to gain the figures on lift force, propulsion, pressure nephogram, velocity diagram and volume fraction distributing of bionic impeller when depth h is at -7.5 cm, 0cm and 7.5 cm, discussed and analyzed the rules of hydrodynamics when h was altering, tamped the groundwork of optimizing the externality design of the bionic impeller further.
