The student's learning outcomes after completing the course

Knowledge:

The student will have a broad knowledge of

• properties of pure substances, phase equilibrium and state equations
• the law of thermodynamics for closed systems
• the law of thermodynamics for open systems with stationary flow
• entropy, state changes, circuit processes, reversible and irreversible processes
• circle processes for power generation and cooling
• the Otto cycle, diesel and gas turbine processes
• refrigeration machines and heat pumps
• heat transfer and heat exchange

Skills:

The student is able to

• carry out energy audits, dimension simple thermal processes, choose working fluids and calculate energy utilization.

Competence:

The student is able to

• apply their knowledge for optimization of energy production, for more efficient energy consumption and for better utilization of renewable energy sources
• write technical reports in the prescribed academic way

Content

The course provides an introduction to the following topics:

• Thermodynamic concepts and definitions
• Thermodynamic systems and features
• Dimensional analysis, energy terminology, thermodynamics, thermal equipment (steam and gas engines, compressors) and plants for the production of energy, including hydropower and district heating plants.
• The energy situation globally and in Norway; alternative forms of energy globally and for partially meeting the Norwegian energy needs
• State equations for the gas phase; tables of thermodynamic properties.
• Work and heat
• The first law of thermodynamics, circle processes, change of state, internal energy, enthalpy, specific heat
• Open systems (control-volume), closed systems, stationary processes
• The second law of thermodynamics, reversible and irreversible processes
• The Carnot cycle, the thermodynamic temperature scale, entropy
• Circle Processes for power generation and cooling
• Air conditioning processes.
• Combustion.
• The Rankine, Otto and Diesel processes
• Gas turbines, combined power plants
• New renewable energy sources (hydro, solar, wind, wave, tidal, osmotic power)
• Refrigerating systems and heat pumps
• Heat transfer, heat conduction, convection, radiation, heat exchangers
• Academic writing: technical reports.

Forms of teaching and learning

The course is taught via lectures, self-study, preparation of technical reports and compulsory exercises. As part of the course students are expected to participate in site or company visits. Topics covered on company visits can be subject to examination.
The course is normally taught in Norwegian, but with participation of international students instruction will be given in English. The course literature, most assignments and some lecture notes are in English.

Coursework requirements - conditions for taking the exam

The details such as exercises and visits to companies are given in the semester plan.
70% of compulsory exercises have to be passed, and all assignments have to be passed and approved before the student is allowed take the final exam.

Examination

A three-hour written examination plus reports. Three out of five technical reports are to be submitted for examination and form part of the student's exam.
Aids permitted are approved formula collections and a calculator

The assessment is given as a letter grade. The grading system A-F is used, where A is the best mark and E is the lowest pass mark. F means failed.
If a student fails the exam, or wishes to improve her/his grade, all exam components have to be submitted again. It can then be possible to improve on previously submitted reports.

Course evaluation

The course is continuously evaluated throughout the semester in accordance with methods approved both by the students and the academic staff. The final course evaluation is in writing.
