Fig. 3: Family of contact-angle models plotting contact angle against capillary number Ca, contrasting the Davis–Hocking, Kistler, and perfect slip cases (core).

The model responses shown on the perimeter incorporate contact-angle hysteresis for the surfaces used in this work. Those in the corners (red framed) indicate model behavior for the range of Ca explored in the current simulations. The other panels show model behavior for alternative Ca ranges.
