Phase-field simulation of core-annular pipe flow [PDF]
International Journal of Multiphase Flow, 2019 Phase-field methods have long been used to model the flow of immiscible fluids. Their ability to naturally capture interface topological changes is widely recognized, but their accuracy in simulating flows of real fluids in practical geometries is not ...

Adaptive phase field simulation of quasi-static crack propagation in rocks
Underground Space, 2018 In this study, we present an adaptive phase field method (APFM) for modeling quasi-static crack propagation in rocks. Crack initiation due to positive strains is considered, and a numerical simulation is implemented using a commercial software, COMSOL ...

Phase-field simulation of solid state sintering
Acta Materialia, 2019 Abstract Manufacturing materials for high performance applications with tailored properties requires a deep knowledge about the sintering process and especially the underlying microstructure evolution. Due to the complex interplay of the material and process parameters as well as complex geometries it is challenging to predict the microstructure ...

STOCHASTIC PHASE-FIELD SIMULATIONS OF SYMMETRIC ALLOY SOLIDIFICATION [PDF]
Fluctuation and Noise Letters, 2004 We study initial transient stages in directional solidification by means of a non-variational phase field model with fluctuations. This model applies for the symmetric solidification of dilute binary solutions and does not invoke fluctuation-dissipation theorem to account for the fluctuation statistics.

Phase Field Simulations of Wetting Based on Molecular Simulations [PDF]
PAMM, 2021 AbstractManufacturing techniques that can produce surfaces with a defined microstructure are in the focus of current research efforts. The ability to manufacture such surfaces gives rise to the need for numerical models that can predict the wetting properties of a given microstructure and can help to optimize these surfaces with respect to certain ...
