Modeling of Non-Isothermal Film Blowing Process for Polyolefines by Using Variational Principles

Abstract

Abstract. In this work, film blowing process analysis has been performed theoretically by using minimum energy approach for non-Newtonian polymer melts considering non-isothermal processing conditions and the obtained predictions were compared with both, theoretical and experimental data (bubble shape, velocity and temperature profiles) taken from the open literature. It has been found that model predictions are in very good agreement with the corresponding experimental data.
