复杂体系流变性及其计算机模拟研究进展

Progress in rheology of several complex systems and its simulation methods

随着科学技术的发展,流变学的研究范围越来越广,同时受到越来越多的重视。本文在概述流变学这门学科基本内容和发展历史的基础上,重点分析了聚合物流体、颗粒流、泡沫以及薄膜润滑这几个热门领域所取得的进展。在描述各领域中流体宏观行为特征的基础上,着重强调物质内在的结构变化以及对应的本构关系的表现形式。同时,鉴于计算的重要性,突出了不同的计算方法在流变学研究上的应用和发展。

With the development of science and technology, the field of rheology is getting boarder and boarder, and is paid more and more attentions. After a brief introduction to the contents and history of rheology, the progress in several hot fields is discussed, involving polymer solution, granular flow, liquid foam, and thin film lubrication. The macroscopic characteristics of these fields are depicted, and the micro-structures together with constitutive laws are stressed. Due to the wide application of computation in rheology, several important methods are described in particular.
