轴流泵复杂空化流动研究进展与展望
Study progress and prospects of complex cavitation flow in axial flow pumps
摘要
Abstract
Axial flow pumps are widely used in many fields,and the complex cavitation flow inside them has a significant impact on the performance,stability,and service life of the pump.In this pa-per,the research on the complex cavitation flow in axial flow pumps was reviewed through both experi-mental and numerical calculation aspects.In the experimental research,the progress achieved by ex-perimental methods such as high-speed photography experiments and laser Doppler velocimetry was mainly introduced.In the numerical calculation,a detailed enumeration and elaboration of a variety of cavitation and turbulence models were carried out,and the application status and development context of numerical simulation methods were analyzed.Combining the research work of experiments and nu-merical simulations,centering on the complex cavitation flow in axial flow pumps,such as attached sheet cavitation,tip leakage vortex cavitation,vertical cavitation vortex,and other phenomena,their respective inception,development,and collapse processes were described.The emphasis was placed on sorting out the characteristics of the tip leakage vortex and its induced unsteady cavitation flow and the mechanism of flow field instability induced by the vertical cavitation vortex under different cavitation numbers and different flow rate conditions.Finally,based on the existing relevant research results of the complex cavitation flow in axial flow pumps,the future research was discussed and projected.关键词
