Materials Processing Fundamentals

The Derby group develops, implements, and employs large-scale numerical modeling to understand processes that are used for the production of advanced solid-state materials, especially bulk, single crystals. Of special emphasis is the representation of three-dimensional and transient continuum transport (flows and heat and mass transport), phase-change phenomena, and process design for a number of melt and crystal growth systems. They are developing and employing a number of parallel finite-element models for these purposes. Specific projects during this period include detailed Bridgman crystal growth modeling, robust solvers for three-dimensional codes, model-based control of crystal growth processes, modeling the dynamics of solution crystal growth, modeling flow and mass transfer in atomic force microscope fluid cell systems, and modeling flow in colloidal crystal growth systems.
