Innhold

The course consists of the following topics:

• The concepts of mass and energy conservation (1st law) and reversibility (2nd law) applied to closed and open (control volume) systems
• Thermodynamic cycles (e.g. thermal power plants, heat pumps, refrigeration)
• Exergy analysis and 1st and 2nd law efficiencies
• Relations between state functions and their derivatives
• Total differentials, partial differentials and their meaning
• Introductory description of thermodynamic energy functions (U, H, A and G), departure functions and thermodynamic reference states
• Selected volumetric equations of state for pure substances and mixtures
• Phase equilibrium in a pure substance, fugacity
• Calculation of vapor-liquid phase equilibrium in mixtures (dew point, bubble point and isothermal flash) by equation of state method and activity models

Arbeids- og læringsformer

Lectures and tutorials are used.

Lectures (based on textbooks) are used to facilitate knowledge and to give a basis for calculations. Demonstrations of calculation programs are also used as a basis for the students’ own calculations. Tutorials are used to develop calculation skills.

Vurderingsformer

Grading is based on an intermediate test which counts 30 % and a final exam which counts 70 % in the final grade.

In order to pass the course, the student must pass the final exam.
