Mesoscale fabrication of a complex surface for integral impeller blades

Xibin WANG,Tianfeng ZHOU,Lijing XIE,Li JIAO,Zhibing LIU,Zhiqiang LIANG,Pei YAN

Frontiers of Mechanical Engineering 2017, Volume 12, Issue 1, Pages 116-131 doi: 10.1007/s11465-017-0426-1

Abstract:

Integral impeller is the most important component of a mini-engine.However, the machining of a mesoscale impeller with a complex integral surface is difficult because ofFor the fabrication of a complex integral impeller, a micro-ball-end mill is designed in accordance withSubsequently, fractal theory is applied to characterize the surface quality of the integral impeller.The fractal theory-based characterization shows that the completed mesoscale integral impeller exhibits

Cavitation in semi-open centrifugal impellers for a miniature pump

LUO Xianwu, LIU Shuhong, ZHANG Yao, XU Hongyuan

Frontiers in Energy 2008, Volume 2, Issue 1, Pages 31-35 doi: 10.1007/s11708-008-0011-8

Abstract: Although both impellers had the same blade cross-section, one impeller had a two-dimensional blade, whileThe average cavitation performance of each impeller was satisfactorily predicted by the numerical simulationscavitation performances as an ordinary-size pump, with the cavitation performance of the semi-open impellerAlso, both the hydraulic and cavitation performance of the semi-open impeller were improved by the leanedThe results also show that uniform flow upstream of the impeller inlet will improve the cavitation performance
