A thin film model for meniscus evolution
Amrita Ghosh, Juan J. L. Velázquez
In this paper, we discuss a particular model arising from sinking of a rigid solid into a thin film of fluid, i.e. a fluid contained between two solid surfaces and part of the flui…

Some thin film models based on Shikhmurzaev's approach
Amrita Ghosh, Barbara Niethammer, Juan J. L. Velazquez
We derive several lubrication approximation models, using Shikhmurzaev's approach to the contact line problem, obtained in \cite{GNV}. The first two lubrication models describe thi…

Revisiting Shikhmurzaev's approach to the contact line problem
Amrita Ghosh, Barbara Niethammer, Juan J. L. Velazquez
In this paper, we revisit a model for the contact line problem which has been proposed by Shikhmurzaev (1993). In the first part, in addition to rederiving the model, we study in d…
