Abstract

This work highlights the complexity of the design process for spiral mandrel dies. There are many degrees of freedom in specifying die geometry, not all of which lead to productive changes in performance. The goal of developing a computer model based upon the fundamental governing equations of flow is to give the designer a tool for analyzing the flow distribution system in such dies. The fact that most of the parameters exhibit critical values for a given die and given criterion of performance, makes the mathematical analysis indispensable. Future improvements which will consider non-isothermal behavior, and multilayer flows will enhance the utility of this tool.
