The flow is controlled by the dynamic “effective” adhesive force. Variation of the free surface velocity ($v^s/{\left(gd\right)}^{1/2}$) (A) and the thickness of the plug ($h_c/d$) (B) with the dynamic “effective” adhesive force $N_c^{eff}$ at $\theta =29^{○}$ for different $N_c$ (different symbols; see Fig. 2 for the key), different $k_n$ (different colors), and different $Q$ (different symbol pattern). The dashed line indicates the transition from a plug-less to a plug-full velocity profile.
