Abstract

The boundary element method is applied to determine particle trajectories close to a pore of a porous surface such as a membrane under Stokes flow. The membrane model is a 3D spatially bi-periodic porous surface with cir- cular holes of finite thickness. The trajectories of spherical particles are obtained from integration of the Newton's second laws using BEM to com- pute the 3D Stokes equations at each time step. Numerical results for both one single particle and a couple of particles are given. 1 Introduction The problem of particle entrapment from a suspension flow past a porous surface with suction has a fundamental application in membrane separation in order to understand the limiting phenomenon of mem
