The dynamics of thin fluid films [PDF]
European Journal of Applied Mathematics, 2001 Not only are thin fluid films of enormous importance in numerous practical applications, including painting, the manufacture of foodstuffs, and coating processes for products ranging from semi-conductors and magnetic tape to television screens, but they are also of great fundamental interest to mathematicians, physicists and engineers.

The Navier-slip thin-film equation for 3D fluid films: Existence and uniqueness [PDF]
Journal of Differential Equations, 2018 We consider the thin-film equation $\partial_t h + \nabla \cdot \left(h^2 \nabla Δh\right) = 0$ in physical space dimensions (i.e., one dimension in time $t$ and two lateral dimensions with $h$ denoting the height of the film in the third spatial dimension), which corresponds to the lubrication approximation of the Navier-Stokes equations of a three ...

Radiative MHD thin film flow of Williamson fluid over an unsteady permeable stretching sheet
Heliyon, 2018 In this research work we have examined the flow of Williamson liquid film fluid with heat transmission and having the impact of thermal radiation embedded in a permeable medium over a time dependent stretching surface.

Stability of thin fluid films characterised by a complex form of effective disjoining pressure [PDF]
Journal of Fluid Mechanics, 2017 We discuss instabilities of fluid films of nanoscale thickness, with a particular focus on films where the destabilising mechanism allows for linear instability, metastability, and absolute stability, depending on the mean film thickness.

Manifold death: A Volume of Fluid implementation of controlled topological changes in thin sheets by the signature method [PDF]
Journal of Computational Physics, 2021 A well-known drawback of the Volume-Of-Fluid (VOF) method is that the breakup of thin liquid films or filaments is mainly caused by numerical aspects rather than by physical ones. The rupture of thin films occurs when their thickness reaches the order of

Influence of Dopant Nature on Biological Properties of ZnO Thin-Film Coatings on Ti Alloy Substrate
Nanomaterials, 2020 In this paper, ZnO and Co2+/Mg2+-doped ZnO thin films on TiAlV alloy substrates were obtained. The films were deposited by spin coating of sol-gel precursor solutions and thermally treated at 600 °C for 2 h, in air and slow cooled.

Effect of curvature on wetting and dewetting of proboscises of butterflies and moths [PDF]
Royal Society Open Science, 2018 Proboscises of butterflies are modelled as elliptical hollow fibres that can be bent into coils. The behaviour of coating films on such complex fibres is investigated to explain the remarkable ability of these insects to control liquid collection after ...

Marangoni flow of thin liquid film underneath a topographical plate
Case Studies in Thermal Engineering, 2022 Marangoni flow occurs when a fluid-fluid free surface is exposed to a non-uniform thermal field. Recently, Marangoni flow has been used to fabricate micro/nano-structures in thin films, which is referred to as thermocapillary patterning.

Application of a Robin boundary condition to surface waves
Frontiers in Marine Science, 2023 Surface effects on deep-water gravity waves are investigated theoretically by the application of a Robin boundary condition with a complex Robin parameter, R=Rr+iRi.
