论文摘要
我们适应复杂液体物理学的统计模型，以研究颗粒状液体的流变学。这使我们能够根据第一原则提供颗粒状流变学法律，这与以前确定的现象学定律相比良好。特别是，在我们的模型中可以将MU（i）流变学的非常成功的定律理解为宏观宏观宏观法律的最低尺寸的非琐碎板。我们模型在Bagnold缩放制度之外描述颗粒物理学的能力可以自然扩展到颗粒状悬浮液的流变学。
We adapt statistical models of the physics of complex fluids to study the rheology of granular liquids. This allows us to provide laws of granular rheology based on first principles, which compare well with previously established phenomenological laws. In particular, the very successful law of mu(I) rheology can be understood within our model as the lowest order non trivial Pade approximant of the macroscopic laws of rheology. Our model's ability to describe granular physics outside of the Bagnold scaling regime allows for a natural extension to the rheology of granular suspensions.
