Skills

The candidate:

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.

An online, part-time version of the PT and EET study programmes will start Fall 2016. An online version of the present course is taught according to the online, part-time PT and EET study programmes. The course will continue to be taught as a traditional campus-based course. The course contents and the learning material used in the course will be the same in both programmes, however, with some differences in the organization of the course: In the online version of the course, there are no ordinary lectures. A number of relevant videos produced by the instructor(s), or external videos, will be provided. These videos will be provided both for the online course and for the campus-based course.

Grading is based on a final exam which counts 100 % of the final grade.
