Content and teaching methods
Mathematical modelling based on continuum mechanics: conservation laws and a hierarchy of constitutive rheological equations (generalized Newtonian fluid, linear viscoelastic models, differential and integral models).
Mathematical modelling based on molecular kinetic theory: how to obtain constitutive equations from molecular models of statistical mechanics, detailed consideration of dilute and concentrated polymer solutions ("Rouse" and "tube" models).
Simple flow problems: analytical solutions using the macroscopic and "molecular"constitutive equations listed above, comparison with experimental data and critical evaluation.
Complex industrial flows: discussion of the basic macroscopic and micro-macro approaches to computer simulation in non-Newtonian fluid mechanics, illustration of modern techniques and recent results.
Introduction to research topics in the field: illustration of current themes based on the lecturer's research activities.

- Exam: oral and open book (50% of final mark); individual work during semester (e.g. to read, report, and present orally a scientific paper) counts for the other 50%.
