Design Guidelines to Balance the Flow Distribution in Complex Profile Extrusion Dies

  • A. Rajkumar , L. L. Ferrás , C. Fernandes , O. S. Carneiro , M. Becker and J. M. Nóbrega


In this work a novel methodology to balance the flow distribution in complex extrusion dies is proposed. For this purpose, the profile cross section geometry is divided into simpler geometries (L and T shaped profiles), which are balanced with a surrogate model obtained by a detailed numerical study. The numerical simulations are performed considering the non-isothermal flow of Bird-Carreau inelastic fluids, and the numerical computations are performed with a solver implemented in OpenFOAM computational library. The proposed methodology is assessed with some case studies.
