【 摘 要 】

We present results of numerical simulation of the drag force acting on a spherical micro-particle in a two-wall channel formed by parallel plates. Dependence of the drag force on the distance between the particle and the channel wall is studied for different channel heights. We show the drag force in a two-wall channel with the height of the order of the particle diameter to be significantly higher than that in the single-wall counterpart.
