Non-Monotonic Marangoni Suppression of Hydrodynamic Coarsening in Bicontinuous Liquid-Liquid Phase Separation
Tian Liu, Haohao Hao, Jiaxi Liu +3
Hydrodynamic coarsening of bicontinuous domains is a central process in liquid-liquid phase separation, yet how soluble surfactants regulate this process remains poorly understood.…
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…
Coalescence induced late departure of bubbles improves water electrolysis efficiency
Tao Wu, Bo Liu, Haohao Hao +4
In water electrolysis, bubbles form on the electrode and interact through processes such as collision and coalescence. However, the impact of bubble coalescence a fundamental proce…
Enhanced Profile-Preserving Phase-Field model of Two-Phase Flow with Surfactant Interfacial Transport and Marangoni Effects
Haohao Hao, Xiangwei Li, Tian Liu +1
Using a regularized delta function to distribute surfactant interfacial concentration can simplify the computation of the surface gradient operator , enabling the phase-f…
