Developing quantitative, multiscale models for microgravity crystal growth.

摘要: Crystal growth conducted under microgravity conditions has had a profound impact on improving our understanding of melt crystal processes. Here, we present brief history and discuss the development appropriate models to interpret optimize these experiments. The need for increased model realism predictive capability demands new approaches describing phenomena important at several disparate length scales. Of special importance is ability represent three-dimensional transient continuum transport (flows, heat, mass transfer), phase-change (thermodynamics kinetics), system design (such as furnace heat transfer during growth). An overview mathematical numerical algorithms employed such multiscale effects presented.
