A Fluid Dynamics Approach for Solid-Liquid Phase Change in Binary and Elemental Melts

Meyer, Stefan

Abstract (englisch):
In this thesis, a simulation model is developed which couples the Navier-Stokes equations as well as transport equations for the temperature and composition field with an independent phase change model based on the phase-field method in a thermodynamic consistent manner. Three validation cases illustrate that the new model can describe experimental observations successfully and that it can improve numerical simulation results of existing modelling approaches.
