Kinetics of dendritic growth under the influence of convective flow in solidification of undercooled droplets

In the present work, the results on dendritic growth with forced convective flow are discussed. The results are obtained for solidification of a pure nickel melt in an electromagnetically levitated droplet. It is shown that the upstream flow imposed on the growing dendrite enhances the growth velocity of the dendritic tips growing in the opposite direction to the flow. Using the model of dendritic growth with convection, we are computing the dendrite growth velocity versus undercooling and explain in part the disagreement of experimental data with previous model predictions for small undercoolings.
