New approach for the modeling of the film blowing process
Original language description
Variational principles were employed to develop the model describing the formation of the bubble in such a way that the resulting bubble shape satisfies the minimum energy requirements. The derived equations for the bubble shape (including HDPE wine-glass shape), take-up force and internal bubble pressure have simple analytical forms with only several physical parameters. The proposed model was used in modeling of the film blowing process for a variety of process conditions and polymer melts taken fromthe open literature, and a very good agreement between measured and simulated data was found.
