加工流场中高聚物复杂流体内部结构的唯象定律

PHENOMENOLOGICAL RELATIONS OF POLYMERIC COMPLEX FLUIDS WITH INTERNAL STRUCTURE IN FLOW FIELDS

讨论了高聚物复杂流体的内部结构张量、热力学状态空间、自由能函数和非平衡热力学唯象定律，综述了唯象定律在处于流场力作用下的高聚物熔体的大分子构象结构、两相共混物的相结构、纤维填充高聚物复合体系的纤维取向结构的流变方程的应用，指出了一条建立流场中高聚物复杂结构流变方程的途径。

In this paper, internal structure tensor, thermodynamic state space, free energy function, and phenomenological relations of non equilibrium thermodynamics for polymeric complex fluids in flow fields were discussed. The phenomenological model is applied to the rheological equations of the macromolecule conformation of polymer melts, as well as the development of phase structure of polymer blending and fiber orientation of polymer compositing. A systematic approach to the rheological modeling of the internal structure of polymer complex fluids is introduced.
