Numerical simulation of coupled flow and heat transfer of fluent metal in the casting process

The design of pouting system for fluent metal is of great importance to casting process design. By the numerical simulation technique, the design of pouring system can be optimized. In this paper, the mathematical model was established for the flow and heat transfer of fluent metal in the casting process, and the determination of the boundary and initial conditions was discussed. Furthermore, a numerical simulation of coupled flow and heat transfer of fluent metal in the casting process was carried out. The results of the simulation were discussed and the important conclusions drawn from this study is very important to the optimization design of casting systems and processes.
