Annotation Bylo provedeno ohodnocení vlivu procesních podmínek, designu vytlačovací hlavy a materiálových charakteristik polymeru na stabilitu procesu vyfukování, a to pro Newtonskou taveninu za předpokladu izotermálních podmínek. Za tímto účelem byl použit nedávno navržený model [Zatloukal, M., Vlcek, J.: J. Non-Newtonian Fluid Mech. 123, p. 201-213, 2004; Zatloukal, M., Vlcek, J.: J. Non-Newtonian Fluid Mech. 133, p. 63-72, 2006] a teoretické predikce byly porovnány s odpovídajícími experimentálními daty. Bylo zjištěno, že predikce modelu jsou v dobré shodě s experimentální realitou.
Annotation in English The effect of processing conditions, die design and material characteristics on the stability of the film blowing process for the isothermal Newtonian melt has been investigated theoretically by the recently proposed Zatloukal-Vlcek model [Zatloukal, M., Vlcek, J.: J. Non-Newtonian Fluid Mech. 123, p. 201-213, 2004; Zatloukal, M., Vlcek, J.: J. Non-Newtonian Fluid Mech. 133, p. 63-72, 2006] and the theoretical predictions were compared with the corresponding experimental data. It has been found that the model predictions are in good correspondence with the experimental reality.

Research Plan 1. Vypracujte literární studii na dané téma.
2. Proveďte teoretickou analýzu stability procesu vyfukování s využitím variačních principů pro Newtonovskou taveninu.
3. Na základě odvozených stabilitních diagramů ohodnoťte vliv reologie Newtonovských tavenin a procesních podmínek na stabilitu procesu vyfukování.
4. Teoretické závěry ověřte s experimentálními daty provedenými na laboratorní vyfukovací lince.
