摘　　要：从分析流体与固体管壁之间的粘附功入手 ,揭示了宾汉流体管内流动时的减阻机理 ,并推导出了宾汉流体的减阻率表达式 ,讨论了各参量对减阻率的影响。With the exploration of adhesive work between fluid and pipe wall,the drag reduction mechanism for the pipe flow of Bingham fluid is brought to light.Further more,the drag reduction rate in pipe flow of Bingham fluid is presented,and effects of relevant factors on the drag reduction rate are discussed systematically.This paper provides a theoretical foundation for the further study on drag reduction.
