Die shape optimization for extrudate swells using feedback control
Author(s): Samdhani Shaik*
In this paper we propose a completely unique approach to unravel the inverse problem of three-dimensional die design forextrudate swell, employing a real-time active
control scheme. to the present end, we envisioned a feedback connectionbetween the corner-line finite element method, wont to predict the positions of the free surfaces of
theextrudate, and therefore the controller. The corner-line method allows for local mesh refinement and transient flow tobe taken under consideration. We show the validity
of this method by showing optimizationresults for 2D axisymmetric extrusion flows of a viscoelastic fluid for various Weissenberg numbers. In 3D wefirst provides a proof
of concept by showing the results of a Newtonian fluid exiting dies with increasing complexityin shape. Finally, we show that this method is in a position to get the specified
extrudate shape of extrudates of avisco.. Read More»
