Parameterized Model Building for Design Optimization

Fluent's consulting services helped our customer develop an efficient CFD methodology to examine the flow-related causes of product non-uniformity in their multi-layer polymer extrusion process. The multi-layer extrusion process employs a spiral distribution section, with a series of concentric flow paths designed to ensure even flow distribution. CFD modeling was pursued in order to examine residence time and shear heating variations that arise in the configuration and lead to product non-uniformity. Circumferential temperature variations due to shear heating, predicted by the CFD models, corresponded to the product non-uniformities observed on the process line.
