IRM20513 Thermodynamics (Spring 2017)

The course is mandatory and included in the bachelor's degree programme in engineering

• Mechanical engineering

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.

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

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.
