摘要: 本文根据卡森液体的流变特性,推导出了该液体在圆管和环形空间内结构流时的流动规律,进而得出了雷诺数的表达式.同时,文章还介绍了怎样用旋转粘度计准确测定卡森液体的流变参数.

Abstract: The casson model is a rheological model which has been used to give a more accurate representation of high shear rate data are available.Based on the rheological characteristics of Casson fluids,the structural flow equations of these fluids in circular pipes and annuli are derived.Furthermore,the expressions of Reynold's number are obtained.How to measure properly the rheological parameters of Casson fluids by rotary viscosimeter is discussed also in this paper.
