PARIONA, Moisés M; SALEM, Guilherme A; BERTELLI, Felipe  e  CHEUNG, Noé. Numerical simulation for prediction of filling process in a sand mould. Rev. LatinAm. Metal. Mater. [online]. 2008, vol.28, n.2, pp.99-110. ISSN 0255-6952.

In this work, the simulation of a filling process for a mold casting was accomplished by the finite elements method. In this study, a Cu-5%Zn alloy solidified in a sand mold was used for numerical modeling. The mold filling process was simulated in atmospheric conditions under gravity and the liquid metal was poured into the mold through a mold channel. The analysis was conducted in the regions of the mold channel, in the mold and at the exit area of the mold, concerning velocity, pressure, temperature, solid fraction and the turbulent kinetic energy of the fluid. The advantage of simulations is to analyze several phenomena present in the mold filling process which are not trivial to be experimentally visualized. The simulation is a powerful tool that permits the analysis and control different parameters, in order to achieve an optimized design to attend the required quality of the cast product.
