Modeling of the Film Blowing Process by Using Variational Principles
Original language description
Variational principles were employed to develop the model describing the formation of the bubble, due to internal bubble pressure and take-up force, 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 varietyof process conditions and polymer melts taken from the open literature, and a very good agreement between measured and simulated data was found.

Modelování procesu vyfukování použitím variačních principů
Czech description
Byl odvozen jednoduchý model analytického tvaru a pro popis procesu vyfukování, a to na základě minimalizace práce odtahové síly a vnitřního přetlaku pro vyfukovaný rukáv. Bylo zjištěno, že navržený model dostatečně přesně popisuje experimentální realitu.
