Abstract
A continuum model for alloy solidification was used to simulate the temperature evolution, solute distribution and liquid flow. The segregation patterns obtained in simulations are consistent with the observations in experiments. The development of segregation in the conditions with different thermal and solute buoyancy forces was analyzed. It is shown that the inhibition of flow can minimize the macrosegregation to the greatest extent. It is also found that the solute partition coefficient determines the segregation pattern and severity in the same fluid flow conditions.
