Analysis of Polymer Flow through Coathanger Melt Distributors

Abstract
Coathanger melt distributors are generally designed on the basis of one-dimensional flow models. These do not always have the desired performance, wherefore a 2-D flow analysis tool was developed based on lubrication approximation theory. This tool uses a contour adapted calculation grid and accounts for manifold side walls. Good agreement is observed for a variety of distributor designs. The integration of this tool into the design process permits to evaluate distributor geometries at design stage, reducing empirical corrections and adjustments.
