Abstract

Fluid-solid systems play a major role in a wide variety of industries, from pharmaceutical and consumer goods to chemical plants and energy generation. Along with this variety of fields comes a diversity in apparatuses and applications, most prominently fluidized and spouted beds, granulators and mixers, pneumatic conveying, drying, agglomeration, coating, and combustion. The most promising approach for modeling the flow in these systems is the CFD-DEM method, coupling computational fluid dynamics (CFD) for the fluid phase and the discrete element method (DEM) for the particles. This article reviews the progress in modeling particle-fluid flows with the CFD-DEM method. A brief overview of the basic method as well as methodical extensions of it are given. Recent applications of this simulation approach to separation and classification units, fluidized beds for both particle formation and energy conversion, comminution units, filtration, and bioreactors are reviewed. Future trends are identified and discussed regarding their viability.

计算流体动力学的可能性和局限性——过程工程中的离散元方法模拟:最新进展和未来趋势的回顾。
流固系统在各种各样的行业中发挥着重要作用,从制药和消费品到化工厂和能源生产。随着这些领域的多样化,设备和应用的多样性也随之而来,最突出的是流化和喷淋床,造粒机和混合器,气动输送,干燥,团聚,涂层和燃烧。对这些系统的流动建模最有前途的方法是CFD-DEM方法,将流体相的计算流体动力学(CFD)和颗粒的离散单元法(DEM)相结合。本文综述了用CFD-DEM方法模拟颗粒流体流动的研究进展。简要概述了基本方法,并对其进行了系统的扩展。本文综述了该模拟方法在分离和分类装置、颗粒形成和能量转换流化床、粉碎装置、过滤和生物反应器等方面的最新应用。确定并讨论其可行性方面的未来趋势。
