Analysis of Flow Behaviour of Non-Newtonian Fluids Habilitation Thesis Summary

Petr Filip

Description of flow behaviour of non-Newtonian fluids participates in modelling practically all polymer processes. The aim of the presented habilitation thesis is to present the results in the following three topics: back extrusion technique, modelling of non-monotonous behaviour of shear viscosity, flow in concentric annuli. Back extrusion technique enables to evaluate the adjustable parameters in basic viscoplastic models with inaccuracy that is fully negligible in practice. This relatively simple and money saving approach thus eliminates usage of sophisticated but very expensive rotational rheometers.
