  • Riahi, Daniel N. (Department of Theoretical and Applied Mechanics (UIUC), 2004-03)
    Steady and oscillatory modes of convective flow in a horizontal mushy layer during alloy solidification are reviewed. The theoretical problem has been based on the model developed by Amberg and Homsy and under the limit ...
