A new Phase-Field Model for Anisotropic Surface Diffusion: Anisotropic Cahn-Hilliard Equation with Improved Conservation (ACH-IC)
Zeyu Zhou, Wei Jiang, Tiezheng Qian +1
As popular approximations to sharp-interface models, the Cahn-Hilliard type phase-field models are usually used to simulate interface dynamics with volume conservation. However, th…

Dynamics of Small Solid Particles on Substrates of Arbitrary Topography
Quan Zhao, Wei Jiang, Yan Wang +3
We study the dynamics of a small solid particle arising from the dewetting of a thin film on a curved substrate driven by capillarity, where mass transport is controlled by surface…

Emergence and Growth Dynamics of Wetting-induced Phase Separation on Soft Solids
Wenjie Qian, Weiwei Zhao, Tiezheng Qian +1
Liquid droplets on soft solids, such as soft polymeric gels, can induce substantial surface deformations, leading to the formation of wetting ridges at contact points. While these…
