Global Asymptotic Solution for Axisymmetric Dendrite Growth with Small Undercooling as long as the surface tension parameter is small enough there always exists a smooth needle like solution for a given undercooling temperature. This non-isothermal needle is close to the Ivantsov parabaloid.

Local Convective Flows in Partly Solidified Alloysw melting point metallic system, Pb-Sn. Such channels are a few (<10) interdendritic spacings wide and several orders of magnitude longer, running approximately vertically; they arise from compositional-density-variations within the interdendritic and bulk liquid regions. The problems of channel nuc

Nonlinear Analyses of Phase Change and Crystal Growth Phenomenaroad class of physical phenomena. The controlled unidirectional solidification of a pure substance or binary mixture under the influence of imposed temperature and/or solute gradients is an example of a phenomena of this sort. For the last twenty years, the morphological stability of freely growing

Global Asymptotic Solution for Axisymmetric Dendrite Growth with Small Undercoolingender. Hence slender body theory is applicable. We obtain a self consistent uniformly valid asymptotic solution to the problems. Our results show that as long as the surface tension parameter is small enough there always exists a smooth needle like solution for a given undercooling temperature. This

Phase Field Models of Free Boundary Problems: Exterior Boundaries Higher Order Equations and Anisotr dynamic problems is considered. A review is presented of recent results which lead to an extension of a Gibbs-Thompson relation. The issue of the intersection of the interface with external (container) boundaries is also discussed.
