Course content

Construction of entropy production for systems with transport of heat, mass and charge. Concentration cells, liquid junctions, membrane transport, electrokinetic effects, Soret, Duffour, Peltier and Seebeck effects. Applications to problems of interest to the student, e.g. fuel cells, chemical processes, thermoelectric effects, salt power plants. The underlying molecular mecahnisms for coupled transport processes are discussed. The energy efficiency of the mentioned processes is in focus. The students take part in a project, theoretical or experimental, formulated in collaboration with the teacher. The purpose is to obtain hands-on experience to use irreversible thermodynamics.

Learning outcome

After finishing the course, the student is expected to:
- Be able to explain the basic postulates in irreversible thermodynamics.
- Be able to derive the entropy production for a simple system with transport of heat, mass and charge.
- Define the energy efficiency of a process with transport of heat, mass and charge.
- Be able to propose equations of transport in agreement with the second law of thermodynamics.
- Understand when such equations are relevant in applications.
- Have written a project report on a typical process where this is relevant.
- Have presented the report for his peers.
- Analyse literature in the field, and apply the theory to two coupled transport processes.

Learning methods and activities

Lectures and exercises. One theoretical or experimental project. English lectures. The student projects will be adapted to the background of the student. Grading is based on the project report and an oral presentation of the work.
