dc.description.abstract	The flow of a polymer melt through a flat spiral distribution system used in "stacked" type dies was analyzed through 3D FEM, and predictions of the exit flow variation were compared to experimental measurements. It was found that for this particular flat spiral die, viscous dissipation is extremely crucial and may lead to generation of hot spots and to increased flow variation.	en
