Enhanced Profile-Preserving Phase-Field model of Two-Phase Flow with Surfactant Interfacial Transport and Marangoni Effects

Autor: Hao, Haohao, Li, Xiangwei, Liu, Tian, Tan, Huanshu

Using a regularized delta function to distribute surfactant interfacial concentration can simplify the computation of the surface gradient operator $\nabla_s$, enabling the phase-field model to effectively simulate Marangoni flows involving surfactan

Coalescence induced late departure of bubbles improves water electrolysis efficiency

Autor: Wu, Tao, Liu, Bo, Hao, Haohao, Yuan, Fang, Zhang, Yu, Tan, Huanshu, Yang, Qiang

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 process governing electrolytic bubble behaviour-on electrolysis efficiency

An Interfacial Profile-Preserving Approach for Phase Field Modeling of Incompressible Two-Phase Flows

Autor: Hao, Haohao, Li, Xiangwei, Jiang, Chenglin, Tan, Huanshu

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 equation effectively captures the topological evolution of complex interf
