Figure 1: The snapshots of simulated dendritic morphology and solute concentration.

(a–c) Evolution of mobile dendrite at solidification time t = 0.32 s, 0.85s, 1.22 s; (d–f) stationary dendrite only considering solutal convection at t = 0.53 s, 1.06 s, 1.96 s. The interval between concentration isolines is 0.1 wt.% with outmost line equal to 4.05wt.%. The dimensionless coordinate values have been scaled by 1000.
