Abstract

A semi-empirical equation is obtained that describes the dependence of shear stress on shear rate during the flow of a one-component suspension. The suspension is considered to consist of two fractions: single grains and their dimers. Equilibrium is established between the two, depending on the shear rate. The equation is based on Krieger’s formula, generalized to multicomponent suspensions. The obtained equation approximates the experimental data and can be used to extrapolate to zero shear rate to determine yield stress.

结构悬浮液流动过程中剪切应力对剪切速率的依赖性

摘要

获得了一个半经验方程，该方程描述了单组分悬浮液流动过程中剪切应力对剪切速率的依赖性。悬浮液被认为由两个部分组成：单个颗粒和它们的二聚体。取决于剪切速率，在两者之间建立平衡。该方程基于 Krieger 公式，可推广到多组分悬浮液。获得的方程近似于实验数据，可用于外推至零剪切速率以确定屈服应力。
