Abstract
Efficient phase field simulation using an adaptive finite volume method is presented for two-dimensional dendritic
growth in a forced flow. The extremely large domain (over 218 in the ratio of cell size), while keeping very small cell size
at the interface, makes the simulation at low supercooling possible. With a strong forced flow, the upstream tip speed
reaches a steady state quickly even at low supercooling. The upstream arm develops side branches easily, but remains
similar after rescaling, i.e., self-affine, as the diffusive one at steady state. r 2002 Elsevier Science B.V. All rights
