Spectrum of growth rates of an isolated dendrite
Brener E. A. , Esipov C. E. , Mel'nikov V. I.
An analysis is made of a mechanism which determines the velocity and direction of the growth of a two-dimensional dendrite and which involves an anisotropy of the surface tension. The growth rate is found in the limit of a slight anisotropy, and it is shown that the dendrite grows in the direction of the lowest surface tension.
