Revisiting Shikhmurzaev's Approach to the Contact Line Problem

In this paper, we revisit a model for the contact line problem which has been proposed by Shikhmurzaev (Int. J. Multiph. Flow 19(4):589-610, 1993). In the first part, in addition to rederiving the model, we study in detail the assumptions required to obtain the isothermal limit of the model. We also derive in this paper several lubrication approximation models, based on Shikhmurzaev's approach. The first two lubrication models describe thin film flow of incompressible fluids on solid substrates, based on different orders of magnitude of the slip length parameter. The third lubrication model describes a meniscus formation where a wedge-shaped solid immerses in a thin film of fluid.

In this paper, we revisit a model for the contact line problem proposed by Shikhmurzaev (1993). We rederive the model and investigate the assumptions required to obtain the isothermal limit. Additionally, we derive several lubrication approximation models based on Shikhmurzaev's approach, including models for thin film flow and meniscus formation.
