摘要
本文以分析流体与固体管壁之间的粘附功为出发点 ,揭示了幂律流体管内流动时的减阻机理 ,并推导出了幂律流体的减阻率表达式 ,讨论了各参量对减阻率的影响。为幂律流体减阻技术的发展提供了理论依据。
The drag reduction mechanism for the pipe flow of power law fluid is brought to light,with the analysis of the adhesive work between fluid and pipe wall.Furthermore,the drag reduction rate in pipe flow of power law fluid is presented,and the effects of relevant factors on drag reduction rate are discussed.This paper provides a theoretical foundation for the development of power law fluid drag reduction technique.
