The research team of this work is involved since the
mid-nineties on the development of computational tools
to aid the design of profile extrusion dies. Initially, the
numerical code employed was based on structured
meshes that limited its application to simple geometries.
The work planned in this PhD programme comprises the
development of a numerical modelling code able to deal
with unstructured meshes and its application on the
design of profile extrusion dies comprising complex
cross sections.
In its current state the numerical code under
development is able to model de flow of generalized
Newtonian fluids inside flow channels using
unstructured meshes.
This paper describes briefly the current state of the
developed code and illustrates its application in a case
study involving the design of a profile extrusion die
comprising a complex cross section
