Abstract
In this paper we compare three frameworks for modeling flows of complex fluids: (i) local conservations of mass, momentum and energy, (ii) GENERIC, and (iii) Onsager principle. The first is based on the mass, momentum, and energy conservation implied by mechanics, the second on the observed approach (in the state space) of externally unforced fluids to thermodynamic equilibrium states, and the third on the approach (in the space of vector fields) of externally driven fluids to dynamics involving less details. The comparison is illustrated on isothermal polymeric fluids.采用GENERIC和Onsager原理进行流变学建模
在本文中，我们比较了模拟复杂流体流动的三种框架：(i)质量、动量和能量的局部守恒，（ii）一般守恒，和（iii） Onsager原理。第一个是基于力学隐含的质量、动量和能量守恒，第二个是基于观察到的（在状态空间中）外部非受迫流体到热力学平衡状态的方法，第三个是基于（在向量场空间中）外部驱动流体到涉及较少细节的动力学的方法。以等温聚合物流体为例进行了比较。

期刊介绍：
The Journal of Non-Equilibrium Thermodynamics serves as an international publication organ for new ideas, insights and results on non-equilibrium phenomena in science, engineering and related natural systems. The central aim of the journal is to provide a bridge between science and engineering and to promote scientific exchange on a) newly observed non-equilibrium phenomena, b) analytic or numeric modeling for their interpretation, c) vanguard methods to describe non-equilibrium phenomena.
Contributions should – among others – present novel approaches to analyzing, modeling and optimizing processes of engineering relevance such as transport processes of mass, momentum and energy, separation of fluid phases, reproduction of living cells, or energy conversion. The journal is particularly interested in contributions which add to the basic understanding of non-equilibrium phenomena in science and engineering, with systems of interest ranging from the macro- to the nano-level.
The Journal of Non-Equilibrium Thermodynamics has recently expanded its scope to place new emphasis on theoretical and experimental investigations of non-equilibrium phenomena in thermophysical, chemical, biochemical and abstract model systems of engineering relevance. We are therefore pleased to invite submissions which present newly observed non-equilibrium phenomena, analytic or fuzzy models for their interpretation, or new methods for their description.
