Modeling of non-isothermal high stalk film blowing process by using variational principles for non-newtonian fluids

Abstract

In this work, the high stalk film blowing model derived by using variational principles has been used to investigate the effect of cooling on the HMW - HDPE bubble formation with respect to final film properties. Moreover, the effect of the molecular weight and long chain branching has been theoretically studied by the help of the newly proposed generalized Newtonian model.
