Numerical simulation has been performed to study the dynamics of the capillary flow in open rectangular channels. The results are compared with the existing experimental data and the analytical solutions in terms of the liquid-gas interface shape, the cross-sectional velocity distributions and the mobility parameter. From the comparison, it is suggested that the agreement between the experimental and analytical results for the mobility parameter reported in the literature is just a coincidence and that further investigation of the flow near the contact-line is necessary to accurately predict the mobility parameter.
