Cascade coalescence dynamically sustains bubble retention near gas-evolving surfaces
Tao Wu, Bo Liu, Haohao Hao +4
Bubble detachment from solid surfaces governs heat, mass, and charge transport across technologies vital to clean energy, including high-current-density water electrolysis and boil…
Weak-electrolyte diffusiophoresis for rigid colloids
Subrata Majhi, Huanshu Tan
We develop a model for the diffusiophoresis of a chemically inert, rigid spherical colloid with fixed surface charge in a monovalent weak electrolyte, in which a neutral solute rev…
Flow instability in Stokes layer of Carreau fluids
Mengqi Zhang, Dongdong Wan, Huanshu Tan
This study investigates the influence of shear-thinning on the instability of a prototype time-periodic flow, the Stokes layer, in Carreau fluids. The time-dependent base flow was…
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…
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…
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…
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…
An Interfacial Profile-Preserving Approach for Phase Field Modeling of Incompressible Two-Phase Flows
Haohao Hao, Xiangwei Li, Chenglin Jiang +1
In this paper, we introduce an interfacial profile-preserving approach for phase field modeling for simulating incompressible two-phase flows. While the advective Cahn-Hilliard equ…
