Abstract

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.
