Abstract

In this paper we present a method to determine the frontlines inside the container and inside the extrusion die based on a steady state velocity field. Using this velocity field the convection equation is solved with a SUPG stabilized finite element method for a variable that represents the time it takes from the initial front to a certain point in the domain. When iso-lines in this field are plotted the development of fronts can be tracked. Extrusion experiments are performed with aluminium billets cut in slices. When extrusion is stopped the billet and extrudate are removed from the container and cut in half in the extrusion direction, copper foils between the slices show the frontlines. These lines show good agreement with the iso-lines from the numerical solution of convection equation
