We present a phenomenological model for granular suspension rheology in which particle interactions enter as constraints to relative particle motion. By considering constraints that are formed and released by stress respectively, we derive a range of experimental flow curves in a single treatment and predict singularities in viscosity and yield stress consistent with literature data. Fundamentally, we offer a generic description of suspension flow that is independent of bespoke microphysics.

基于约束的颗粒分散流变学方法

我们提出了一种颗粒悬浮流变的现象学模型，其中颗粒相互作用作为对相对颗粒运动的约束进入。通过分别考虑由应力形成和释放的约束，我们在一次处理中得出了一系列实验流动曲线，并预测了与文献数据一致的粘度奇异性和屈服应力。从根本上讲，我们提供了独立于定制微观物理学的悬浮液流动的一般描述。
