Resumo

The problem motivating the current work is a mould filling during casting process. The aim of our analysis is to provide a simple experimental model simulating the main flow characteristics accompanying such process. Hence, the hot fluid is supplied under high pressure into an inclined box. Fluid flows inside the box between two cold isothermal walls, passing obstacles simulating internal complexity of a mould. The main features of a casting process, like a free surface flow and increase of the fluid viscosity followed by solidification, are investigated in the model. Opposite to a real casting, this experimental configuration allows for full control of the experimental conditions and the full field measurements of the temperature and velocity fields. Collection of the quantitative transient data of the flow should allow for verification and validation of the numerical models used for typical casting problems. Our main aim is to create an experimental benchmark for the mould-filling problem.
