| Abstract: | Numerical simulation equations were established for the mold filling process of liquid metal with turbulent or laminar flows and for the process of liquid metal being solidified and cooled into the casting. The solution methods for the equations and the treatment methods for related boundary conditions and latent heat were introduced. Based on these equations, the programs for calculating the 3-D velocity and temperature fields, pre-processing, post-processing and database were made. Finally, these programs were assembled a 3-D numerical simulation software named SRIFCAST for mold-filing and solidification processes of the cast alloys. This simulation software has been applied to design casting technology for various castings, especially for investment castings, and the sound castings were obtained by using SRIFCAST. |
