    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.
