Influence of the phase diagram on the diffuse interface thickness and on the microstructure formation in a phase-field model for binary alloy

Selzer, Michael; Nestler, Britta; Danilov, Denis - In: Mathematics and Computers in Simulation (MATCOM) 80 (2010) 7, pp. 1428-1437

A phase-field model is used to investigate the responses of planar interfaces and of eutectic microstructures on the different shapes of the phase diagram in binary alloy systems. Numerical solutions of the dynamic field equations show that the interfacial profile and the thickness of the...

A phase-field method for interface-tracking simulation of two-phase flows

Takada, Naoki; Misawa, Masaki; Tomiyama, Akio - In: Mathematics and Computers in Simulation (MATCOM) 72 (2006) 2, pp. 220-226

For interface-tracking simulation of two-phase flows with a high density ratio, we propose a computational method, NS–PFM, combining Navier–Stokes (NS) equations with phase-field model (PFM) based on the free energy theory. Through the numerical simulations, it was confirmed that (1) the...
