Thermodynamics in Energy Conversion


Due to the recent events regarding the corona virus, this lecture/exercise will be available online via Moodle as recordings to all students.

Updates and information can be found in the corresponding Moodle course or on our website.

If you have any queries, please contact the corresponding assistants of the lecture by e-mail. Most concerns can be clarified without face-to-face contact.

We apologize for any inconvenience, and stay healthy.


This course deals with the thermodynamic principals behind the energy conversion process. Students will be taught which thermodynamic behaviors of various conversion processes and technologies they will be required to understand and evaluate.


First part of the lecture: Fundamentals

Choosing system boundaries, mass and energy balances, first and second law of thermodynamics, open and closed systems, phase equilibria, steam tables, entropy and irreversibilities, process changes and thermodynamic cycles, exergy analysis

Part two: Application to energy conversion processes

  • Steam cycle: principle, calculation, optimization, comparison with ORC
  • Gas turbine: efficiency, optimization, combination with steam circuits (combined cycle),
  • CHP Refrigeration cycles: Cycles, Joule-Thomson effect, refrigerants, heat pumps
  • Chemical reactions: basic concept, stoichiometry, energetic and thermodynamic aspects, combustion reactions
  • Fuel cells: principle, advantages, calculation, electrolysis Advanced definitions of exergy to fuels (chemical exergy, exergy factors, heating value)
  • Thermal energy storage: Application, Calculation, transient balances

Further Information

This lecture is part of the master program POWER ENGINEERING. Students from the bachelors or masters program Mechanical Engineering, regardless of their area of study, may take these two modules as supplementary subjects (registration for the courses on TUMonline).
