Universität Wien FIND

Return to Vienna for the summer semester of 2022. We are planning to hold courses mainly on site to enable the personal exchange between you, your teachers and fellow students. We have labelled digital and mixed courses in u:find accordingly.

Due to COVID-19, there might be changes at short notice (e.g. individual classes in a digital format). Obtain information about the current status on u:find and check your e-mails regularly.

Please read the information on https://studieren.univie.ac.at/en/info.

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

Polymers show an unusual mechanical response when a stress or strain is applied. The response is between solid-like and fluid-like. Therefore, polymers are an example for a complex fluid. In the lecture we will use basic considerations on the intra- and intermolecular interactions of macromolecules to discuss models for the complex viscoelastic properties of polymers and polymer solutions. The viscoelasticity of polymers also gives rise to the formation of glasses. This will also be presented in the lecture. Applying thermodynamic and statistical methods which are known from the Bachelor courses in Physical Chemistry we will study the following topics:
- ideal elastic behaviour of an ion lattice
- 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 (in solution)
- glass transition of polymers

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

Methods:
Lectures, problems

For the time being the lectures will be digital offline or online via Moodle. The offline lectures will be supported by a 45 minutes review session/flipped classroom.
