Crossover Scaling in Dendritic Evolution at Low Undercooling

Materials Science 2009-10-31 v2 Disordered Systems and Neural Networks Soft Condensed Matter

Abstract

We examine scaling in two-dimensional simulations of dendritic growth at low undercooling, as well as in three-dimensional pivalic acid dendrites grown on NASA's USMP-4 Isothermal Dendritic Growth Experiment. We report new results on self-similar evolution in both the experiments and simulations. We find that the time dependent scaling of our low undercooling simulations displays a cross-over scaling from a regime different than that characterizing Laplacian growth to steady-state growth.
