Abstract

The aim of our analysis is to provide a simple experimental model simulating the main flow characteristics accompanying casting processes. Hence, a hot liquid is provided under high pressure into an inclined box. The liquid propagates inside the box between two cold isothermal walls, passing obstacles simulating internal complexities of a mould. The main features of the experiment like flow acceleration and deceleration due to the obstacle, a free surface flow and sudden increase of the fluid viscosity as it cools down, are typical for a solidification of melt in a mould. As opposed 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.
