Description:
In this investigation, an A356/10%100μm SiCp upward suction casting with a cylinder cavity of 40 mm diameter and 400 mm height was conducted with stirring technique. The SiCp contents in the casting different sections were quantitatively measured with micro digital image analysis system, and then were compared and analyzed. To simulate the casting mold filling, the composite mixture was simulated based on the Euler method while the particulate flow was calculated with the Lagrangian method for predicting the SiCp distribution. The flow of the mixture and particulate phases was analyzed and discussed. The simulated particulate distribution was compared and validated with the experimental results. Both results have shown that the particulate contents decreased along the upward mold filling direction, and that the particulates were prone to be trapped near the mold wall at the filling beginning part due to local lower temperature and higher viscosity and they distributed towards th...
