Computationally efficient phase-field models with interface kinetics

摘要

We present a new phase-field model of solidification which allows efficientcomputations in the regime when interface kinetic effects dominate overcapillary effects. The asymptotic analysis required to relate the parameters inthe phase-field with those of the original sharp interface model isstraightforward, and the resultant phase-field model can be used for a widerange of material parameters.
