Title

AIR PRESSURE SIMULATION IN CASTING MOLDS

Pages

  15-23

Abstract

 During MOLD FILLING, molten metal can only advance as quickly as the air inside the cavity is expelled. In this work an analytical model describing air flow is developed based on a incompressible flow theory. AIR PRESSURE has serious effects upon the filling behaviour such as surface profile and filling time. In this work a new mathematical model is proposed for calculation the AIR PRESSURE during the MOLD FILLING. A single phase computational fluid dynamic code based on the SOLA-VOF algorithm used for prediction the fluid flow. Air discharged through the vents is modelled by ideal gas assumption, conservation of mass equation and Bernoulli law. A new algorithm was developed to interpolates the AIR PRESSURE on the surface cell. The creation of air back pressure was correlated with sizes of vents and pouring basin height. In order to verify the computational results a series of experimental test was conducted. Comparison between the experimental data and SIMULATION results has shown a good agreement.
