| The accurate prediction of the solidification interface is a key issue in crystal growth process. The interface shape depends on the heat transfer in the melt and on its thermal environment. Hence, global computation is mandatory for an accurate prediction. |
|
All the simulation results presented below have been performed in collaboration with IKZ (Institut für Kristalzüchtung, Berlin, Germany), and UCL (Université Catholique de Louvain, Louvain-la-Neuve, Belgium).

The goal of these simulations is to reproduce the experimental measurements of the solidification interface shape. Striations in the photo-scanning resistivity measurements of the ingot are compared to the numerical simulation results.

| Photo-scanning resistivity measurements revealing the shape of the solidification interface and numerical stream function for the following crystal rotation rates: (top) 5 RPM, (middle) 10 RPM, (bottom) 15 RPM. An excellent agreement between the numerical calculations and the experiments is observed. |
