A kidolgozandó feladat címe: Phase-field modelling of multi-phase solidification including the effect of melt convection
A téma rövid leírása, a megoldandó legfontosabb feladatok felsorolása:

Our computational materials science group have been modelling solidification processes for more than 15 years. In our everyday work, this usually means setting up phase-feld and phase-feld crystal models which result in partial differential equations that can be solved numerically. Most often we do this by our own simulation codes that we run on our CPU or GPU-based computer clusters.

Most problems we investigate are connected to the microstructure formation during solidification, i.e., the nucleation and the subsequent crystal growth. Because of its key role in determining the final properties of the matter, understanding and controlling microstructure formation is of fundamental practical importance. The job of the PhD student to be recruited is also connected to this subject area. He/she will be involved in the work related to an ESA project, which aims at the modelling of lamellar microstructures formed during coupled peritectic solidification, without and then with taking into account the effect of gravity induced melt flow. By comparing the results, the student has to determine the effect of the melt flow on the boundaries of the stability domains of the different microstructures and has to compare the simulation results to the terrestrial and microgravity experiments of the project partners.

The successful applicant will work as a member of our small team. We provide the high performance GPU workstations for the research and the possibility of presenting his/her work in international meetings and conferences.
