论文摘要
我们提出了一种基于Stribeck曲线的统一机制，以使颗粒之间的摩擦系数捕获剪切稀疏 - 牛顿高原 - 剪切增厚 - 低 - 中间 - 临界 - 高剪切速率的剪切稀薄的流变行为，分别用于典型的高剪切速率，以造成典型的致密非透明液。我们通过将数值结果与实验数据进行比较来建立所提出的模型的准确性。非DLVO（Derjaguin和Landau，Verwey和Overbeek）的存在以及摩擦系数随着垂体变形而降低的摩擦系数可以分别以高剪切速率以中间剪切速率和第二个剪切稀薄的速度来解释牛顿高原的存在。
We propose a unifying mechanism based on the Stribeck curve for the coefficient of friction between the particles to capture the shear thinning - Newtonian plateau - shear thickening - shear thinning rheological behavior at low - intermediate - beyond critical - high shear rates, respectively, for a typical dense non-Brownian suspension. We establish the accuracy of the proposed model by comparing the numerical results with experimental data. The presence of non-DLVO (Derjaguin and Landau, Verwey and Overbeek) forces and a coefficient of friction reducing with asperity deformation explain the existence of the Newtonian plateau at the intermediate shear rates and the second shear thinning regime at high shear rates, respectively.
