Modul: Rheologie und Rheometrie

The students have acquired all competences to describe and model the behavior of complex fluids after completion of this module. They understand all key concepts and know where complex fluids are important for practical purposes. They are enabled to recognize, characterize, describe and deal with complex fluids. Thanks to accompanying exercises with hands-on in the lab, the students are additionally able to conceive and carry out the measurements necessary to characterize the viscous and/or elastic behavior of fluids and to interpret the obtained results.

  • Content:
Many fluids come with non-Newtonian properties. Those influence viscous losses, transport properties, product quality, and material properties. Considering the high viscosity of most products, the lecture concentrates mostly on laminar flow conditions and is structured as follows:
·         Basics of Rheology and Rheometry, introducing viscosity
·         Movement of a fluid, Couette flow and its solution
·         Newtonian fluids
·         Shear-thinning and shear-thickening fluids, power law
·         Yield stress, Bingham fluids
·         Thixotropy and rheopexy
·         Analytical flow solutions in a pipe
·         Capillary viscometers
·         Rotational rheometers
·         Visco-elastic fluids, Maxwell model, complex fluid properties
·         Oscillation rheometers
·         Reiner-Rivlin fluids, generalized Newtonian fluids
·         Elongational viscosity, relation of Trouton
·         Rheological description of blood
