Analysis of Fluid Flow in Mixer with Phyllotaxically Arranged Blades
Based on the principle of structural bionics,this paper establishes the models of passive mixer with blades applying whorled,opposite-whorled and cyclic phyllotaxy arrangement,respectively.Computational fluid dynamics(CFD)method is adopted for numerical simulation of the mixer models.Analyzes the relationship between blade arrangement and effect of fluid flow,and investigates the influence of different blade pitches with the same blade arrangement.The results show that when applying the same blade pitch,cyclic phyllotaxy has the best flow flow,followed by opposite-whorled phyllotaxy,and whorled phyllotaxy is the worst;for whorled phyllotaxy and opposite-whorled phyllotaxy,fluid flow improves with increase of blade pitch;for cyclic phyllotaxy,fluid flow improves with the decrease of blade pitch.
