Phase-field simulation of solidification with moving solids

This thesis presents a novel methodology for simulating solidification using fluid structure interactions coupled with the phase-field method while allowing for topology changes in the solid-liquid interface with non-stationary solids. This methodology is implemented using a finite difference scheme and a semi-implicit integration method. Pure translation and pure rotation cases are demonstrated and a preliminary simulation of applied shear on a particle is presented. These results demonstrate that the model shows promise for understanding the behavior of various systems like semi-solid metals, polymer mixtures, and moving solids undergoing chemical reactions.
