Information

Aims, contents and method of the course

Content:
Part 1: Fluid Properties
The availability of reliable data on material properties is essential in chemical engineering and for industrial process layout. This lecture presents an overview of modern methods for the estimation of several physical-chemical properties in fluids. Pure substances as well as mixtures will be explored. Such estimations methods which are saving costs and allow for quick results compared to detailed measurements are heavily used in chemical engineering and process technology all over the world.

The following topics will be tackled:
Critical and other properties of pure substances
PVT properties of pure substances
PVT properties of mixtures
Selected thermodynamic properties
Properties of ideal gases
Vapour pressure and vaporisation enthalpy
Transport properties

Goal 1:
Understanding of application oriented methods for physical-chemical fluid property estimations

Part 2: Viscoelasticity of Polymers: a glimpse into a complex system

The fluids discussed in part 1 show usually 'normal' Newtonian behaviour. Opposite polymers show an unusual mechanical response when stress or strain is applied. The response is partially solid-like and partially fluid-like. Therefore, polymers are an example for a complex non-Newtonian fluid. In the lecture you will learn about models how to describe viscoelastic behaviour. Starting from the non-Newtonian behaviour of polymer solutions the viscoelastic behaviour of polymers will be discussed. Applying thermodynamic and statistical methods which are known from the Bachelor courses in Physical Chemistry we will study the following topics:
- ideal elastic behaviour
- relaxation processes
- ideal fluid behaviour in Newtonian fluids
- introduce a model for viscoelastic behaviour
- polymer conformation
- polymer solutions
o dilute
o semi-dilute
- viscoelastic properties of polymers and polymer solutions

Goal 2: basic understanding of viscoelastic behaviour and dynamics with focus on macromolecules.
