DIRECTIONAL SOLIDIFICATION IN MICROGRAVITY
摘要
A fixed grid single domain approach (enthalpy method) has been used to study the directional solidification of binary alloys in a Bridgman furnace. The effects of thermal and solutal convection are included. Numerical solutions using both a vorticity-stream function formulation and the flow code CFX with a primitive variable formulation are presented for the solidification of an alloy of bismuth with 1 at % tin in a microgravity environment.
