Liquid fraction
liquid in the cavity, as the initial condition established previously. The results
show a linear evolution of the melted fraction. There is a good agreement among
the numeric and experimental results, obtained by the images processing, although
it can be noted that the experimental points are clearly below the curve obtained by
the numeric procedure. That is, for the same time, the melting front in the numeric
simulation moves faster than for the experiments.
