Abstract

The phase field crystal (PFC) model is a conserved continuum model which isused to investigate the phase behavior of materials near the melting point. The simplestPFC model, used in the present work, produces solid, liquid, and lamellar phases. Thesolid phase features a spatially periodic triangular lattice structure much like the crystalstructure of some real materials. The present work focuses on the development of computer codes to solvenumerically the differential equations of the PFC model using a Fourier spaceformulation. These programs are then used in studies of dendritic growth and Ostwaldripening. Results of the Ostwald ripening study are compared to experimental data ofdiffusion-limited growth of solid Sn domains in a liquid solution of Pb and Sn inmicrogravity. Possible next steps for this project are discussed.
