Heat-transfer model assessment of chill rolls for polymer film extrusion.

Summary

In cast film extrusion, the polymer melt drops onto a chill roll in a tangential contact, where it freezes into a film. Eight heat-transfer models with diverse levels of lumping and distribution were developed for the casting of polymeric films on chill rolls. Three models were found to be suitable to describe this operation. The most convenient model to use is the one having temperature distribution in the film and lumping in the shell, and it allows for the easy incorporation of the contact heat-transfer coefficient.
