Drops on polymer brushes: advances in thin-film modeling of adaptive substrates

S Hartmann, J Diekmann, D Greve, U Thiele - Langmuir, 2024 - ACS Publications
We briefly review recent advances in the hydrodynamic modeling of the dynamics of
droplets on adaptive substrates, in particular, solids that are covered by polymer brushes …

Recent advances in and future challenges for mesoscopic hydrodynamic modelling of complex wetting

U Thiele - Colloids and Surfaces A: Physicochemical and …, 2018 - Elsevier
We highlight some recent developments that widen the scope and reach of mesoscopic thin-
film (or long-wave) hydrodynamic models employed to describe the dynamics of thin films …

Dynamics of thin liquid films on vertical cylindrical fibres

H Ji, C Falcon, A Sadeghpour, Z Zeng, YS Ju… - Journal of Fluid …, 2019 - cambridge.org
Recent experiments on thin films flowing down a vertical fibre with varying nozzle diameters
present a wealth of new dynamics that illustrate the need for more advanced theory. We …

Sessile drop evaporation in a gap–crossover between diffusion-limited and phase transition-limited regime

S Hartmann, C Diddens, M Jalaal… - Journal of Fluid …, 2023 - cambridge.org
We consider the time evolution of a sessile drop of volatile partially wetting liquid on a rigid
solid substrate. The drop evaporates under strong confinement, namely, it sits on one of the …

Stick-slip dynamics in the forced wetting of polymer brushes

D Greve, S Hartmann, U Thiele - Soft Matter, 2023 - pubs.rsc.org
We study the static and dynamic wetting of adaptive substrates using a mesoscopic
hydrodynamic model for a liquid droplet on a solid substrate covered by a polymer brush …

Mesoscopic hydrodynamic model for spreading, sliding, and coarsening compound drops

J Diekmann, U Thiele - Physical Review Fluids, 2025 - APS
We revisit the mesoscopic hydrodynamic description of the dynamics of sessile partially
wetting compound drops, ie, of drops that consist of two immiscible nonvolatile partially …

Soft wetting with (a) symmetric Shuttleworth effect

C Henkel, MH Essink, T Hoang… - … of the Royal …, 2022 - royalsocietypublishing.org
The wetting of soft polymer substrates brings in multiple complexities when compared with
the wetting on rigid substrates. The contact angle of the liquid is no longer governed by …

Gradient dynamics model for drops spreading on polymer brushes

U Thiele, S Hartmann - The European Physical Journal Special Topics, 2020 - Springer
When a liquid drop spreads on an adaptive substrate the latter changes its properties what
may result in an intricate coupled dynamics of drop and substrate. Here we present a …

[HTML][HTML] Three-dimensional nonlinear dynamics of a thin liquid film on a spinning ellipsoid

S Duruk, RG Shepherd, E Boujo, M Sellier - Physics of Fluids, 2023 - pubs.aip.org
The present work investigates the three-dimensional flow of a thin liquid film distributed on
the outer surface of an ellipsoid, rotating around the vertical axis at constant angular velocity …

Flow-driven collapse of lubricant-infused surfaces

ES Asmolov, TV Nizkaya… - Journal of Fluid …, 2020 - cambridge.org
Lubricant-infused surfaces in an outer liquid flow generally reduce viscous drag. However,
owing to the meniscus deformation, the infused state could collapse. Here, we discuss the …
