Learning outcome

Knowledge:
The course provides the student with knowledge about:
- Conservation laws for mass and energy (including the 1st law of Thermodynamics).
- Forms of energy such as work (power) and heat, internal energy and enthalpy.
- Entropy and the 2nd law of thermodynamics.
- Reasons for thermodynamic losses in the form of irreversibilities.
- The quality of different forms of energy measured as the ability to produce work.
- Destruction of energy quality in processes.
- Ideal gas model, its assumptions, applications and limitations.
- Different cyclic processes such as Carnot, Rankine, Otto, Diesel and Brayton.
– The course gives the student insight about:
- Operation of steam and gas based power stations, internal combustion engines, heat pumps and refrigeration cycles.
- The main components of heat & power processes, such as steam and gas turbines, compressors, pumps, fans, heat exchangers and valves.
- The ability of fluids to change phase (solid, liquid and gas).
Skills:
The course should enable the student to:
- Estimate thermodynamic properties for systems by the use of tables and graphical diagrams.
- Calculate efficiencies for power producing and power consuming processes.
- Describe thermodynamic processes in graphical diagrams such as pv, Tv og Ts.
General competence:
The course should give the student:
- Basic competence that constitute central elements in other courses focusing on energy systems and industrial processes.
- Understanding of systems and the capability to evaluate the efficiency of processes w.r.t. energy and exergy (energy quality).
- Overview of processes for power production, heating (heat pumps) and cooling (refrigeration cycles).

Learning methods and activities

Lectures. Weekly assignments. One group assignment during the semester (a larger thermodynamic analysis/laboratory assignment).

Compulsory assignments

• Exercises
• Small project

Further on evaluation

Approved compulsory activity (assignments and semester project) will be valid for all later exams in the course.

You have to pass the semester assignment and 2/3 of the weekly assignments in order to take the final exam. A postponed written exam ("kontinuasjonseksamen") can be changed to an oral exam.

Specific conditions

Recommended previous knowledge

None.
