摘要：
Fluids in porous media driven by the capillaryforce are greatly affected by capillary's geometrical structure. The steady flow in a non-uniform capillary is numerically analyzed by the finite element method. With the given initial and boundary conditions, the flow velocity distribution with different geometrical parameters is obtained, and the result is in a good agreement with the experimental data.
