# Calculation of solidification phenomena with CFDRC

My name is Josep Maria Vilarrasa Diaz, studying mechanical engineering at the unversity of of Girona.
Thanks to the DAAD, I visited the IMET from July to September 2003.
During my visit at IMET, I learned to use CFDRC based on the task to calculate
solidification phenomena.
My report can be found here (

MS-Word File,

PDF File).
I can also provide a step-by-step tutorial for calculating a simple solidification problem with
CFDRC (

PDF).
The material property data used for the calculations are provided here:

Using that temperature dependent material properties,
we studied the solidification of iron and aluminium in a quadratic (200x200mm) crucible made
of alumina (low heat conductivity) or metal (high conductivity).
We did a 2-D calculation and we were calculating
only the upper right 25%,
an assumption which is correct for the calculations without fluid flow.
We studied the following cases:

- Aluminium with aluminium crucible and no fluid flow effects.
- Aluminium with alumina (Al
_{2}O_{3}) crucible and no fluid flow effects
Solidification time 150s, temperature map depending on time
800x600 AVI Video, 32MB.
- Iron with iron crucible and no fluid flow effects
- Iron with alumina (Al
_{2}O_{3}) crucible and no fluid flow effects
Solidification time 660s, liquid fraction map depending on time
1024x768 AVI Video, 37MB,
temperature map depending on time
1024x768 AVI Video, 33MB.
- Iron with alumina (Al
_{2}O_{3}) crucible and including natural convection (fluid flow) effects:
Solidification time 450s, liquid fraction map depending on time
1024x768 AVI Video, 55MB,
temperature map depending on time
1024x768 AVI Video, 146MB
and finally, temperature and flow field:

.

For the continuation of this work, the flow calculations can be made more physical and shrinkage
effects may be considered.
