Isogeometric Phase-Field Simulation of Boiling
2016In this work we consider the Navier–Stokes–Korteweg equations, a diffuse-interface model describing liquid–vapor phase transitions. A numerical scheme for this model is constructed based on functional entropy variables and a new time integration concept.

A Scalable Implicit Solver for Phase Field Crystal Simulations
2013 IEEE International Symposium on Parallel & Distributed Processing, Workshops and Phd Forum, 2013The phase field crystal equation (PFC) is a popular model for simulating micro-structures in materials science and is very computationally expensive to solve. A highly scalable solver for PFC modeling is presented in this paper. The equation is discredited with a stabilized implicit finite difference method and the time step size is adaptively ...

Phase-field-crystal simulation of nonequilibrium crystal growth
Physical Review E, 2014By using the phase field crystal model, we simulate the morphological transition of the crystal growth of equilibrium crystal shape, dendrite, and spherical crystal shape. The relationship among growth morphology, velocity, and density distribution is investigated.

Phase-field simulations of partial melts in geological materials
Computers & Geosciences, 2009A diffuse interface description based on a multi-phase-field model for geological grain microstructures is introduced, especially useful in the treatment of partially molten structures. Each grain as well as different phases are represented by individual non-conserved order parameters, the phase fields @f"@a, which are defined on the complete ...

Extreme Scale Phase-Field Simulation of Sintering Processes
2019 IEEE/ACM 10th Workshop on Latest Advances in Scalable Algorithms for Large-Scale Systems (ScalA), 2019The sintering process, which turns loose powders into dense materials, is naturally found in the formation of glaciers, but is also the indispensable process to manufacture ceramic materials. The dynamically evolving microstructure, which is established during this process, largely influences the resulting material properties.

Phase-Field Modeling and Simulation of the Zone Melting Purification Process
SIAM Journal on Applied Mathematics, 2014Summary: Zone melting is an efficient purification method that is widely used in the manufacture of semiconductors. Recently, it has been used in the purification of industrial phosphorus [\textit{Z. Zhang} et al., ``Purification of phosphorus by a zero pollution zone melting technique'', Sep. Purif. Tech.

Phase field simulations of ferroelectric materials
2014Ferroelectric materials have become preferred materials in a wide variety of electronic and mechatronic devices due to their pronounced dielectric, piezoelectric, and pyroelectric properties. The material macroscopic properties are related to the microscopic domain structure of the materials.

The phase field simulation of autocatalytic nucleation
2017Precipitation of metastable θ′ phase is a well known process that underlies age-hardening of Al-Cu alloys. The strength acquired is very sensitive to the morphology and spatial distribution of θ′, with the peak hardness corresponding to a fine distribution of precipitates with high length-to-thickness aspect ratio.
