| Aim: To provide an introduction to rheology and flow of polymeric liquids. |
Contents: The course is devoted to five main topics:
1. Introductory fluid mechanics: Equations of change on the basis of fluxes. Equations of change with transport properties. Solution of isothermal and nonisothermal flow problems.
2. Rheology of polymeric liquids: Viscosity of Non-Newtonian fluids, viscoelastic effects, bubbles and particles, nondimensional groups, characterization of polymeric fluids by material functions.
3. Models for polymeric fluids: the generalized Newtonian fluids, linear viscoelasticity, nonlinear viscoelasticity.
4. Solution of flow problems: Rheometry, extrusion, formation of fibres and film, injection moulding, heat treatment of foodstuffs etc.
5. Analysis of experimental measurements. Classical methods: Steady and oscillatory shear flow. New Methods: Transient elongation. |
