A direct method of solidification for the enhancement of mushy zone network models

Network models allow to study fluid flow around numerous grains during solidification. It appears that the predicted behavior of a network model depends heavily on the rate of solidification estimated for each individual channel. Therefore, a suitable 1D solidification model is investigated with direct methods. The model includes heat, solute and mass conservation as well as the Wilson-Frenkel formula. An accurate but CPU-time consuming method is presented.
