颗粒流体数学模型研究进展

Research advance in granular flow mathematical model

颗粒流广泛存在于工农业生产过程中,分析颗粒体系的流体动力学特征越来越受到众多科研工作者的关注,但是人们对于其机理认识的还不深入。介绍了描述颗粒流动的数学模型,深入分析了各个模型的适用范围和优缺点,探讨了目前存在的问题和今后研究的重点。

Granular flow exists widely in the production process of industry and agriculture. Scientists pay more and more at- tention to the analysis of fluid dynamic features of particles, but the mechanism is not well understood yet. The mathematical model of granular flow is introduced, and the scope of application, the advantages as well as the shortcomings of various models are analyzed. The existing problem and the key points to be studied in the future are discussed.
