Is contact-line mobility a material parameter?

ABSTRACT: Dynamic wetting phenomena are typically described by a constitutive law relating the dynamic contact angle θ to contact-line velocity U_CL. The so-called Davis-Hocking model is noteworthy for its simplicity and relates θ to U_CL through a contact-line mobility parameter M, which has historically been used as a fitting parameter for the particular solid-liquid-gas system. The recent experimental discovery of Xia & Steen (2018) has led to the first direct measurement of M for inertial-capillary motions. This opens up exciting possibilities for anticipating rapid wetting and dewetting behaviors, as M is believed to be a material parameter that can be measured in one context and successfully applied in another. Here, we investigate the extent to which M is a material parame
