Finite element modelling of flow distribution in an extrusion die

1 Finite element modelling of flow distribution in an extrusion die [Pg.173]

We consider a co-extrusion die consisting of an outer circular distribution channel of rectangular cross-section, connected to an extrusion slot, which is a slowly tapering narrow passage between two flat, non-parallel plates. The polymer melt is fed through an inlet into the distribution channel and flows into [Pg.173]

The described algorithm may not yield a converged solution in particular for values of power law index less than 0.5. To ensure convergence, in the iteration cycle (h + 1) for updating of the nodal pressures, an initial value found by [Pg.174]
