Abstract
The influence of convection on the concentration field in front of a growing lamellar eutectic was determined numerically for 50% and 33% volume fraction eutectics. The results were used to calculate the change in lamellar spacing λ, assuming the eutectic grows at the spacing giving the minimum interfacial undercooling. The value of λ increases with the square of the stirring intensity, especially at low growth rate V. Large increases in λ can occur for typical crystal growth situations. The fictitious stagnant film model yields erroneous results that predict little effect of convection on λ and an incorrect dependence of λ on position along the interface.
