本文提出了一种液体絮凝剂覆盖的固体颗粒团聚模型。该模型不是在粒子接触时通过耗时的碰撞动力学数值模拟得出的，而是基于解析关系：因此计算成本显著降低。该模型被实现为一个计算机代码，使用欧拉-拉格朗日方法模拟一组粒子，即它形成了一种有吸引力的替代离散元素模拟(DEM)的方法。此外，还对剪切流动系统进行了数值模拟，并与理论模型进行了比较。(C)2014爱思唯尔有限公司。保留所有权利。
The present paper proposes a model for agglomeration of solid particles covered with a liquid flocculant. Rather then being derived by time-consuming numerical simulations of collision dynamics as the particles are in contact, the model is based on analytic relations: thus the computational cost is significantly reduced. The model was implemented into a computer code simulating a set of particles using the Eulerian-Lagrangian approach, that is, it forms an attractive alternative to Distinct Element Modelling (DEM). Moreover numerical simulations in a shear-flow system were done and the results were compared with a theoretical model. (C) 2014 Elsevier Ltd. All rights reserved.
