Efficient numerical scheme for a dendritic solidification phase field model with melt convection

Journal of Computational Physics, 2019
In this paper, we consider numerical approximations for a dendritic solidification phase field model with melt convection in the liquid phase, which is a highly nonlinear system that couples the anisotropic Allen-Cahn type equation, the heat equation ...

Domain wall state diagram for SrTiO3/BaTiO3 superlattice structures

Journal of Advanced Dielectrics, 2023
The domain wall structure of ferroelectric/ paraelectric superlattices can be much more complex due to the influence of the superlattice stacking structure, the in-plane strain induced by the substrate and environmental temperature.

Phase-Field Model of Mode III Dynamic Fracture

, 2001
We introduce a phenomenological continuum model for mode III dynamic fracture that is based on the phase-field methodology used extensively to model interfacial pattern formation.

A thermodynamically consistent phase-field model for two-phase flows with thermocapillary effects [PDF]

, 2014
In this paper, we develop a phase-field model for binary incompressible (quasi-incompressible) fluid with thermocapillary effects, which allows for the different properties (densities, viscosities and heat conductivities) of each component while ...

Physical phase field model for phagocytosis

New Journal of Physics
We propose and study a simple, physical model for phagocytosis, i.e. the active, actin-mediated uptake of micron-sized particles by biological cells.

Combining phase field crystal methods with a Cahn-Hilliard model for binary alloys [PDF]

, 2017
During phase transitions certain properties of a material change, such as composition field and lattice-symmetry distortions. These changes are typically coupled, and affect the microstructures that form in materials.

A phase-field model for fluid-structure interaction [PDF]

Journal of Computational Physics, 2018
In this paper, we develop a novel phase-field model for fluid–structure interaction (FSI), that is capable to handle very large deformations as well as topology changes like contact of the solid to a wall.

Crack Propagation of Ground Insulation in Electric Vehicle Drive Motor End-Winding Based on Electromechanical Coupling Phase Field Model

World Electric Vehicle Journal
Grounding insulation is a key component of electric vehicle drive motors, and cracks may appear during the manufacturing process and assembly. In this paper, the novel method of coupling phase field, mechanic field and electric field is proposed to ...

Linear and unconditionally energy stable schemes for the binary fluid–surfactant phase field model [PDF]

, 2017
In this paper, we consider the numerical solution of a binary fluid–surfactant phase field model, in which the free energy contains a nonlinear coupling entropy, a Ginzburg–Landau double well potential, and a logarithmic Flory–Huggins potential.
