Abstract:

The important result reported is that under a distinguished limit procedure an alternative to the K-S Equation is obtained when modelling the evolution of solidification fronts. Three papers are being prepared for publication. Solidification Fronts Asymptotic equations are derived to model the evolution of the solid liquid interface which occurs in the directional solidification of binary alloys. In the limit where GDVCog fc is small, the Kuramoto-Sivashinsky equation is obtained. Viscous Phase Transition Two equations are derived and analyzed which model the dynamics of viscous first order phase transitions.
