TY - JOUR TI - Numerical analysis of a steady flow in a non-uniform capillary AU - Li Ya-Ping AU - Wang Li-Li AU - Fan Jie JN - Thermal Science PY - 2020 VL - 24 IS - 4 SP - 2385 EP - 2391 PT - Article AB - Fluids in porous media driven by the capillary force 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.
