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.

过程工程中计算流体动力学离散元方法模拟的可能性和局限性:近期进展和未来趋势的回顾。

从制药和消费品到化工厂和能源生产,流固系统在众多行业中都扮演着重要角色。随着各种领域的发展,设备和应用也发生了变化,其中最突出的是流化床和喷射床,制粒机和混合机,气动输送,干燥,附聚,涂覆和燃烧。在这些系统中对流动进行建模的最有前途的方法是CFD-DEM方法,将流体相的计算流体动力学(CFD)与颗粒的离散元方法(DEM)耦合。本文回顾了使用CFD-DEM方法建模颗粒-流体流的进展。简要概述了基本方法及其方法性扩展。这种模拟方法在分离单元和分类单元中的最新应用,审查了用于颗粒形成和能量转化的流化床,粉碎装置,过滤和生物反应器。确定并讨论了未来趋势的可行性。
