We investigate the well-posedness of a phase-"eld model for the isothermal solidi"cation of a binary alloy due to Warren}Boettinger [12]. Existence of weak solution as well as regularity and uniqueness results are established under Lipschitz and boundedness assumptions for the non-linearities. A max
Using state-of-the-art numerical techniques, such as mesh adaptivity, implicit time-stepping and a non-linear multi-grid solver, the phase-field equations for the non-isothermal solidification of a dilute binary alloy have been solved. Using the quantitative, thin-interface formulation of the proble
The development of accurate and efficient computational tools for phase transformation is a prerequisite in order to predict the microstructure evolution during phase transformation in engineering alloys. Even though the antitrapping phase-field model (PFM) has been developed and is increasingly bei
A similarity solution for a multicomponent solidification model is introduced. The model includes a complete coupling of solute and temperature fields in the mushy region, a eutectic reaction, macrosegregation, microsegregation and fluid flow. The similarity solution is demonstrated on comparing its
