Abstract

^__ Semi-empirical equations are derived that describe the dependence of shear stress on shear rate during the flow of a one-component suspension. The suspension is considered as consisting of two fractions: single grains of the solid phase and their dimers, between which a reversible dimerization reaction occurs. In this case, the dimerization of single grains is considered as a reaction with an invariable rate constant, and the dissociation of dimers is considered as an inverse reaction with a rate constant that increases linearly with the shear rate. The equations are based on the Krieger−Doherty formula, generalized to the case of a multicomponent suspension.

触变和流变悬浮液的流变学

摘要

^__推导出半经验方程，描述单组分悬浮液流动期间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：固相的单个颗粒及其二聚体，在它们之间发生可逆二聚反应。在这种情况下，单颗粒的二聚化被认为是速率常数不变的反应，而二聚体的解离被认为是速率常数随剪切速率线性增加的逆反应。这些方程基于 Krieger−Doherty 公式，推广到多组分悬架的情况。
