摘要:

在这篇文章中,两个新的数值方法已被开发用于模拟三维(3D)Stokes流中的流体/多孔颗粒相互作用。多孔颗粒内的流体流动采用Brinkman-Debye-Bueche模型,颗粒外的流体流动采用Stokes方程。用这两种新方法研究了有界剪切流中多孔球的旋转运动和两个多孔球的相互作用。数值结果表明,多孔颗粒的渗透率对两个多孔球的相互作用有很大的影响。

英文摘要:

In this article, two novel numerical methods have been developed for simulating fluid/porous particle interactions in three-dimensional (3D) Stokes flow. The Brinkman-Debye-Bueche model is adopted for the fluid flow inside the porous particle, being coupled with the Stokes equations for the fluid flow outside the particle. The rotating motion of a porous ball and the interaction of two porous balls in bounded shear flows have been studied by these two new methods. The numerical results show that the porous particle permeability has a strong effect on the interaction of two porous balls.
