Semisharp phase field method for quantitative phase change simulations

, 2003
The standard phase field model for simulation of phase change requires an asymptotic analysis in a vanishing interface width, in order to connect the model parameters to the sharp interface parameters, which has hampered the quantitative usefulness of ...

Constitutive Modelling of Sintered Steel by Phase-field Method

Procedia Structural Integrity
The phase-field method is lately one of the most popular approaches for modelling of complex fracture phenomena. As known, the displacement field and phase-field variable cannot be determined simultaneously, except for easy problems, due to non-convexity of the energy functional.

Topology Optimization for Microfluidic Mixers by a Phase Field Method

International Journal for Numerical Methods in Fluids
ABSTRACT We investigate multi‐physical topology optimization for microfluidic mixers. Starting from the Ising model, we derive a thermodynamically consistent Ginzburg–Landau free energy functional that incorporates the objective functional as an effective external field, providing a physically interpretable framework for phase‐field ...
