Metal Casting Technologies : June 2007
To deal with the problem where the domain keeps decreasing, a very simple moving wall boundary condition is employed. It is emphasized that in the description of plunger moving the grid system in the domain remains unchanged. We chose a method of maximum preserving the calculating system before. In this method, the moving wall is treated such as the second fluid in the multi-phase flow calculations. Fig. 1 shows the flow chart of the calculating code. EXPERIMENTAL MODEL The water modeling instrument for the visualization experiments was made to prove the accuracy of the developed shot sleeve flow pattern simulation module as shown in Fig. 2. It includes a transparent plastic acrylic shot sleeve, a plunger, and the 1D robot system which can control the plunger speed of shot sleeve. The space between the plunger and the sleeve end is 60mm in diameter and 500mm in length.
