Quantitative isothermal phase-field simulations of peritectic phase transformation in FeMn system

Journal of Materials Research and Technology, 2016
The present investigation shows quantitative results for the peritectic phase transformation of FeMn alloys utilizing phase-field simulations in 1-D and 2-D. The phase-field method used was based on an adaptation of the proposal of Folch and Plapp [Phys.

A phase-field-crystal approach to critical nuclei

, 2010
We investigate a phase-field-crystal model for homogeneous nucleation. Instead of solving the time evolution of a density field towards equilibrium we use a String Method to identify saddle points in phase space.

Bubble flow analysis using multi-phase field method [PDF]

EPJ Web of Conferences
In simulations of gas-liquid two-phase flows using conventional interface capture methods, we observed that when bubbles come close to each other, they tend to merge numerically, despite experimental evidence indicating that they would repel each other ...

Some Remarks on the Neutrino Oscillation Phase in a Gravitational Field [PDF]

, 2000
The weak gravitational field expansion method to account for the gravitationally induced neutrino oscillation effect is critically examined. It is shown that the splitting of the neutrino phase into a ``kinematic'' and a ``gravitational'' phase is not ...
