Deterministic Behaviour in Sidebranching Development
The development of sidebranching in solidifying dendrites in a regime of finite diffusion length is studied both experimentally and by means of a phase-field model. The growth rate of each sidebranch shows a power-law behaviour from the early stages of its life. From their birth, branches which finally succeed in the competition process of sidebranching development have a greater growth exponent than branches which are stopped.
