This model experiment is described in detail in the reference [Gandin, Ch-A. “From constrained to unconstrained growth during directional solidification.” Acta Materialia 48.10 (2000)] https://www.sciencedirect.com/science/article/pii/S1359645400000707
The model experiment has the following caracteristics:
| Caracteristics of the model experiment | |
|---|---|
| Alloy | Al - 7wt%Si |
| Geometry | 1D or pseudo 1D. Height = 0.1 m |
| Boundary conditions | Fourier condition at the bottom; adiabatic conditions everywhere else |
| Domains | fully liquid; mushy zone (liquid + dendrites); fully solid (eutectic + dendrites) |
For all test cases, the temperature and the fraction of solid are recorded according to time on sensors placed every 2 cm along the height of the geometry.
Here are different ways to model this experiment:
Using the front tracking method (matlab script)
Using thermic solvers in cimlib
