Abstract

A novel runner system design, named a Vortex-Gate, has been explored for aluminium gravity casting. Using this design, the velocity of flow of the liquid metal was controlled below the critical velocity and, at the same time, a high flowrate was maintained. The flow behaviour achieved did not appear to generate either bifilm or bubble defects. The 'virtual' experiment using a computational modelling package, and the 'physical' experiment, a real-time X-radiography study, were found to be in reasonable agreement.
