Design of complex profile extrusion dies through numerical modeling

The achievement of a balanced flow is one of the major tasks encompassed in the design of profile extrusion dies [1]. For this purpose numerical modeling codes may be a very useful aid. The research team involved in this work has been working during the last decade on the development of numerical tools to aid the conception of extrusion dies [1,2]. The design code developed so far carries out the automatic sear...

Flow balancing in complex geometry profiles extrusion dies

One of the most complex tasks involved in the design of profile extrusion dies, is to obtain a balanced flow, which can be simplified through the employment of numerical modelling tools [1]. This work is part of a broader project that has been developed during the last years [1,2], and comprises the development of adequate numerical modelling codes to aid the design of extrusion dies. The initial version of the...

Numerical modelling code based on the finite volume method in unstructured grids

In this work, the implementation employed in the new modeling code is described. It is based on the FVM with on a SIMPLE type scheme suitable for unstructured meshes.

Development of numerical tools to aid the design of complex geometry profile ex...

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...
