A Diffuse-Interface Marangoni Instability
Xiangwei Li, Dongdong Wan, Haohao Hao +3
We investigate a novel Marangoni-induced instability that arises exclusively in diffuse fluid interfaces, absent in classical sharp-interface models. Using a validated phase-field…

Profile-Preserving Phase-Field Model for Surfactant Transport and Adsorption-Desorption in Two-Phase Flow Systems
Haohao Hao, Xiangwei Li, Luyun Xu +2
The diffuse-interface model for two-phase flows with soluble surfactants has garnered considerable attention due to its ability to circumvent the need for Robin boundary condition…

Marangoni Interfacial Instability Induced by Solute Transfer Across Liquid-Liquid Interfaces
Xiangwei Li, Dongdong Wan, Mengqi Zhang +1
This study presents analytical and numerical investigations of Marangoni interfacial instability in a two-liquid-layer system with constant solute transfer across the interface. Wh…
