Bridgman Crystal Growth of an Alloy With Thermosolutal Convection Under Microgravity Conditions

摘要

The solidification of a dilute alloy (bismuth-tin) under Bridgman crystal growth condi- tions is investigated. Computations are performed in two dimensions with a uniform grid. The simulation includes the species concentration, temperature and flow fields, as well as Conduction in the ampoule. Fully transient simulations have been performed, with no Simplifying steady state approximations.
