Shrinkage-Induced Fluid Flow and Domain Change During Solidification of Pure Substances
A mathematical model is established to investigate the shrinkage effect for a unidirectional solidification of pure metals or eutectic alloys. A front tracking method using the fixed-grid and two-moving-node technique is employed in numerical calculations. In this method, one moving node is used to track the sharp solid-liquid interface, while the global domain change is recorded by the other moving node. Calculations are performed to obtain the transient temperature distribution, velocity distribution, solid-liquid interface location, global domain size, and total solidification time. For comparison, the corresponding solidification is also computed assuming no shrinkage effect. It is found from this study that the shrinkage-induced fluid flow and domain change can have significant effects on the temperature distribution and solidification time.
