Abstract
Level set method is an appropriate mathematical tool for solving two-phase flow problems. It is used here for the first time to track the interface ev olution during the process of casting a second alloy into mold, partly disp lacing the first to achieve a casing with a different alloyed skin. Project ion method for Navier-Stokes equations was adopted and the algorithm was im plemented in finite element method. The numerical example shows that though in those cases where the layer of liquid metal above is lighter than that below, the interface is not always stable for density ratios less than one of the two liquid metals. The stability of the interface is sensitive to th e density ratio and inlet velocity and relatively insensitive to the viscos ity ratio or other parameters. It is believed that level set method has pot ential to be further used in real double casting processes. (C) 2001 Elsevi er Science B.V. All rights reserved.
