1Simulation of micro-behaviors including nucleation,growth,and aggregation in particle system显示文摘A new method for the solution of population balance equations(PBE) describing the micro-processes such as nucleation,growth,aggregation of particle swarms in a multiphase system is proposed.The method is based on the fixed pivot moment and allows arbitrary number of moments to be tracked si-multaneously.By expressing PBEs for both batch and continuous operations in a general form,and using weighted residual method to derive the moment equations,different moments can be tracked directly.The numerical density function is assumed to be a summation of several weighted Dirac Delta functions,and the integral and derivative terms in PBEs are transformed to a summation in order to reduce computational cost.Simulations of a batch nucleation-growth process and a continuous ag-gregation-growth process have demonstrated good agreement with the corresponding analytical solu-tions,with relative errors less than 108%.Simulation of a combined nucleation-growth-aggregation process,which does not have an analytical solution,is also included,so as to reproduce the mi-cro-behaviors of such a complex system,demonstrating the feasibility and reliability of this method.GU ZhaoLin SU JunWei JIAO JianYing XU X Yun 2009Science China Chemistry2009,52,2:4
2颗粒系统成核、长大、聚并微观行为的模拟显示文摘针对描述多相体系中成核、长大、聚并微观过程的群体平衡方程,提出了一种可以跟踪任意数目矩的定点矩方法.为便于方法处理,将间歇式和连续式两种不同操作过程下的群体平衡方程写成统一形式,并利用权值残差法导出统一形式矩方程,实现了两种操作条件下矩的直接跟踪.将数值密度函数简化为连续DiracDelta函数加权和,将积分或微分转化为连续求和.对连续式操作下的成核、长大微观过程和间歇式操作条件下的聚并、长大微观过程模拟结果表明:该方法具有较高数值精度,与分析解的相对误差在10-8%以内.对无分析解间歇式操作过程中成核、聚并、长大复合微观过程模拟,重现了复合过程微观行为,说明该算法的可行性.苏军伟 焦建英 顾兆林 X Yun Xu 2008中国科学(B辑)2008,38,9:3
