摘　　要：结晶是许多工业和科学应用中的重要过程,涉及复杂的传质、传热以及流体动力学问题。传统实验方法很难获得结晶过程全部细节参数,直接影响产品的性能和质量。基于计算流体力学(CFD)的结晶过程模拟,可以在结晶动力学定量模型的基础上对结晶过程及晶体产品质量进行预测分析,在结晶过程设计、结晶方法开发以及结晶器放大等领域具有重要作用。基于此,重点综述了粒数衡算方程的几种数值解法,并详细介绍了其在溶析和反应结晶过程中耦合CFD计算模拟,以及在结晶器放大设计中的应用情况,最后展望了CFD-PBE在工业结晶中的研究趋势与发展方向。The crystallization process is an important process in many industrial and scientific applications.However,there are complex mass transfer,heat transfer,and fluid dynamics problems in crystallization process.It’s difficult for traditional experimental methods to grasp all the details of the crystallization process,which directly affects the performance and quality of products.Crystallization process simulation based on computational fluid dynamics(CFD)can be used to predict and analyze crystallization process and crystal product quality.Moreover,some quantitative models of crystallization kinetics can be also used in the crystallization process design,crystallization method development,scale-up of crystallizer and other fields.Thus,this article focuses on several numerical solutions of particle balance equations,and provides a detailed introduction of CFD-PBE simulation.The practical applications of this couple solving method in anti-solvent crystallization process,reactive crystallization process and crystallizer design process were also discussed.Finally,the research trends and development directions of CFD-PBE in industrial crystallization are prospected.
