Advanced operator splitting based semi-implicit spectral method to solve the binary and single component phase-field crystal model [PDF]
, 2011 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.We present extensive testing in order to find the optimum balance among errors associated with time integration, spatial discretization, and splitting for a

Phase-field modelling for atoms [PDF]
, 2023 The application of phase-field modelling has been expanded into smaller and smaller-scale phenomena. However, phase-field modelling with a single atomic resolution has not been proposed so far.

Simulation of Dendritic-Eutectic Growth with the Phase-Field Method
Acta Materialia, 2023 Solidification is an important process in many alloy processing routes. The solidified microstructure of alloys is usually made up of dendrites, eutectics or a combination of both. The evolving morphologies are largely determined by the solidification process and thus many materials properties are dependent on the processing conditions.

Phase-field simulation of grain nucleation, growth, and Rayleigh distribution of U3Si2 nuclear fuel
Frontiers in Energy Research, 2023 U3Si2 is a potential accident-tolerant fuel (ATF) due to its high thermal conductivity and uranium density relative to UO2. The grain size and distribution play an essential role in the service performance of U3Si2.

Improved Polymer Crystal Phase Field Model and Numerical Simulation
Mathematics, 2022 The existing phase field model of polymer crystallization contains many parameters that lack actual physical meaning. Although the value of these parameters can be adjusted to obtain results consistent with the experiment, it cannot correspond to the ...

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.

Science and Technology of Advanced Materials: Methods, 2023 In phase-field simulations, accurate material parameters are required to quantitatively predict microstructural evolutions. Non-sequential data assimilations enable the estimation of unknown material parameters by minimizing a cost function that ...
