Modeling interfacial dynamics with soluble surfactants in a multiphase system is a challenging task. Here, we consider the numerical approximation of a phase-field surfactant model with fluid flow. The nonlinearly coupled model consists of two Cahn–Hilliard-type equations and incompressible Navier–Stokes equation. With the introduction of two auxiliary variables, the governing system is transformed into an equivalent form, which allows the nonlinear potentials to be treated efficiently and semi…

This work develops an efficient energy stable scheme for the hydrodynamics coupled phase-field surfactant model with variable densities and rigorously proves that the proposed scheme is unconditionally energy stable.

Interfacial dynamics with soluble surfactants: A phase-field two-phase flow model with variable densities

A discontinuous Galerkin method for a diffuse-interface model of immiscible two-phase flows with soluble surfactant

The proposed scheme is shown to decay the total free Helmholtz energy at the discrete level, which is consistent with the continuous model dynamics, and recovers the Langmuir adsorption isotherms at equilibrium.

We consider the numerical approximation of the binary fluid surfactant phase-field model confined in a Hele-Shaw cell, where the system includes two coupled Cahn-Hilliard equations and Darcy

Thermodynamically consistent modelling of two-phase flows with moving contact line and soluble surfactants

Droplet dynamics on a solid substrate is significantly influenced by surfactants. It remains a challenging task to model and simulate the moving contact line dynamics with soluble surfactants. In

Stabilized Energy Factorization Approach for Allen–Cahn Equation with Logarithmic Flory–Huggins Potential

This paper proposes a novel energy factorization approach with the stabilization technique, which is called stabilized energy factorsization approach, to deal with the Flory–Huggins potential and shows that all nonlinear terms can be treated semi-implicitly and the resultant numerical scheme is purely linear and easy to implement.

Numerical Approximations for the Cahn–Hilliard Phase Field Model of the Binary Fluid-Surfactant System

This paper develops two linear and decoupled, first order and a second order time-stepping schemes using the so-called "invariant energy quadratization" approach for the double well potentials and a subtle explicit-implicit technique for the nonlinear coupling potential.

Linear, Second order and Unconditionally Energy Stable schemes for a phase-field moving contact line Model

In this paper, we consider the numerical approximations for solving a hydrodynamics coupled phase field model consisting of incompressible Navier-Stokes equations with generalized Navier boundary

Simulating binary fluid-surfactant dynamics by a phase field model

In this paper, the dynamics of a binary fluid-surfactant system described by a phenomenological phase field model is investigated through analytical and numerical computations. We first consider

Analysis of finite element approximations of a phase field model for two-phase fluids

It is shown that the proposed numerical methods satisfy a discrete energy law which mimics the basic energy law for the phase field model and the convergence to the phaseField model and to its sharp interface limiting model are established.

Phase-field models provide a way to model fluid interfaces as having finite thickness. This can allow the computation of interface movement and deformation on fixed grids. This paper applies
