摘要

用管式粘度计研究了牛粪浆料的流变特性。先前提出的流变模型(Che, 1986)用于描述管壁处的剪切应力和剪切速率之间的关系。结果与旋转粘度计的结果进行了比较。定义了一个修正雷诺数，并将其用于描述管内层流的摩擦损失。文中还讨论了层流区域终止处的雷诺数。

Laminar tube flow of sieved beef-cattle manure slurries

The rheological properties of beef-cattle manure slurries were studied using a tube viscometer. The previously proposed rheological model (Che, 1986) is used to describe the relationship between the shear stress and shear rate at the tube wall. The results are compared with those obtained with a rotational viscometer. A modified Reynolds number is defined and used to relate to the friction loss of the laminar flow in the tube. The Reynolds numbers where the laminar flow region terminated are also discussed.
