Effect of Mass Flow in Melt on the Motion of theCrystal-Melt Interface of Hard Spheres: A MolecularDynamics Study

Abstract

Following a previous molecular dynamics investigation on thehard-sphere crystal-melt interface, effects of mass flow in themelt on the interface motion are reported. After preparingsystems using the method of Mori et al. [Phys. Rev. E51 (1995) R3831], slight initial flow velocities were addedto the melts. Interface motions caused by the density increase anddecrease due to the flow were observed. It is shown that thisphenomena can reasonably be understood from the viewpoint of massconservation.
