Abstract
A multiphase model was applied to simulate a core shooting process numerically. At the beginning of the research programme, simulations of the core shooting process with simple core box geometry (e.g. cylindrical core box) were carried out to examine the general applicability of the model used. In the next stage, simulations of core box geometry with complex flow behaviour of the sand–air motion were carried out to test the possibility of application of the model to industrial core box geometries. All the simulations were done in two and three dimensions. Experiments were carried out to validate the simulation results. Good agreement between simulation and experimental results indicates that the implemented multiphase model is suitable for modelling the core shooting process. Finally, the results of the simulation of core shooting of industrial core (wheel hub) are presented.
