本文提出了一种新的、热力学一致的颗粒流体混合物模型,该模型由m<s:1> ller和Liu的熵原理导出。包括结合额外孔隙压力概念的压力扩散方程,以及材料的欠塑性行为,对本构量施加了热力学限制。该模型应用于颗粒流体流动,并结合流体压力使用封闭假设。虽然工作的重点是概念部分,即热力学一致性建模,但也进行了简单剪切流的数值模拟,得到了物理上合理的结果。
This paper presents a new, thermodynamically consistent model for granular-fluid mixtures, derived with the entropy principle of Müller and Liu. Including a pressure diffusion equation combined with the concept of extra pore pressure, and hypoplastic material behavior, thermodynamic restrictions are imposed on the constitutive quantities. The model is applied to a granular-fluid flow, using a closing assumption in conjunction with the fluid pressure. While the focal point of the work is the conceptional part, i.e. the thermodynamic consistent modeling, numerical simulations with physically reasonable results for simple shear flow are also carried out.
