    On the characterisation of the Vočadlo fluids using a back extrusion technique

  • Original language description

    Back extrusion represents one of the cheapest and time-saving experimental methods how to determine rheological characteristics of the fluids studied. This method is based on plunging of a circular rod into an axisymmetrically located circular cup containing the experimental sample. Formerly this method was successfully applied to power-law, Bingham and Herschel-Bulkley fluids. The aim of this contribution is to present a sufficiently simple user-friendly procedure how to determine the individual rheological parameters appearing in the Vočadlo model (sometimes called Robertson-Stiff one) - yield stress, consistency parameter and flow behaviour index.

    K charakterizaci Vočadlova modelu pomocí postupu zpětného vytlačování

  • Czech description

    Metoda zpětné extruse se řadí k levnějším a časově úspornějším metodám, pomocí kterých lze vyhodnotit parametry vybraných reologických modelů jako např. mocninného či Herschelova-Bulkleyho. Tento příspěvek se zabývá určením hodnot parametrů pro Vočadlůvmodel.
