Modeling the Manufacture of Fibers
The goal of these lectures is to convey a body of work that has emerged from our research group through serious interactions with a fiber manufacturer. We will report on the basic research issues of mathematical and physical nature which necessarily arise in the attempt to model and understand the fiber manufacture process. As we will convey, the processing of technical and textile fibers is very complex, involving multiple filaments of polymeric molten material which are being drawn as fast as possible without causing breaks, with significant temperature changes to solidification before the take-up location. The models and codes have to be accurate enough and yet tractable in order to explore variations in the fibers due to processing conditions upstream and downstream, material properties, and flow conditions.
