Краткое описание

In this note, an exact solution is presented for the flow produced by a plate oscillating with arbitrary periodic oscillation in a porous medium. The velocity field is composed of a steady state part and a transient part. It is found that the flow depends on the permeability parameter. The velocity profiles and the wave penetration depth are damped in the transverse direction due to the existence of the porous medium. The influence of the porous medium on the oscillation increases with the increase of the permeability parameter.

Ключевые слова: oscillating plate, porous medium, Stokes' problem
