提出了一种计算固液（粘弹性）混合物流动中大量颗粒（颗粒移动器）运动的数值方法。在该方法中，液体和固体的完全耦合的运动使用有限元技术来解决，和固体颗粒的悬浮流体施加的流体动力和力矩的作用下移动。开发的软件包是能够模拟粒子在几个流行的非牛顿粘弹性流体模型的运动。
A numerical method for computing motions of large numbers of particles (particle mover) in flows of solid-liquid (viscoelastic) mixtures was developed. In the method the fully coupled motions of liquid and solid are solved using a finite element technique, and solid particles move under the action of the hydrodynamic forces and moments exerted by the suspending fluid. The developed package is able to simulate the motion of particles in several popular models of non-Newtonian viscoelastic fluids.
