Solid adsorption: the missing mechanism for surfactant contact lines -- a phase-field approach
Parvathy K. Kannan, Kazi T. Iqbal, Diego DÃaz +5
We develop a thermodynamically consistent phase-field model for soluble surfactants in two-phase flows, incorporating both interfacial and solid surface adsorption. The model is de…
Cahn-Hilliard Phase Field modelling captures nanoscale contact line dynamics on high-friction surfaces
Michele Pellegrino, Parvathy K. Kannan, Gustav Amberg +3
Incorporating molecular-scale effects in the description of contact line motion is essential for accurately capturing all sources of energy dissipation in wetting dynamics. This ho…
Turbulent heat transfer in open-channel flows with a thermally-conductive porous wall
Seyed Morteza Habibi Khorasani, Geert Brethouwer, Shervin Bagheri
Results of direct numerical simulations (DNS) of porous-wall turbulent flows in open channels with conjugate heat transfer are reported in this work. For the conductive porous wall…
Local slip length and surfactant effects on liquid-infused surfaces
Sofia Saoncella, Julien Cerutti, Théo Lenavetier +3
Robust surfaces capable of reducing flow drag, controlling heat and mass transfer, and resisting fouling in fluid flows are important for various applications. In this context, tex…
Optical Coherence Tomography in Soft Matter
Kasra Amini, Cornelius Wittig, Sofia Saoncella +3
Optical Coherence Tomography (OCT) has become an indispensable tool for investigating mesoscopic features in soft matter and fluid mechanics. Its ability to provide high-resolution…
