Modelling and simulation of the freeze casting process with the phase-field method

• Freeze-casting phase-field model including particle size effects is presented. Simulations for various sizes and solidification conditions are conducted. Scaling laws microstructural lengths derived based on simulations. The freeze casting process a novel manufacturing method both near net-shape parts as well directed porous structures employed by filters implants. Depending the choice of liquid processing very wide range pore shapes can be achieved. In order to predict resulting microstructure, developed basis grand potential formalism. its parametrization approximate freeze-casting water linking thermodynamics with established theory. Directional simulations varying suspension concentrations, velocities temperature gradients carried out. From these, determined linked parameters, so derive linkages between microstructure conditions.
