College of Materials Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, ChinaReceived 20 April 2006; accepted 30 June 2006Abstract: The solution algorithm (SOLA) method was used to solve the velocity and pressure field of the thermal flow fllingprocess, and the volume of fluid (VOF) method for the free surface problem. Since the“donor-acceptor rule often results in the freeinterface vague, the explicit difference method was adopted, and a method describing the free surface state at0
