Title
Thermodynamics
ECTS
7.5
Prerequisites
Mechanics, Mathematics 1
Purpose
To give students knowledge about the fundamental laws and methods in thermodynamics and enable the student to solve idealized thermodynamical problems on both individual components and systems.
Content
• Thermodynamic states and parameters.
• Heat and work.
• 1st law of thermodynamics for closed systems.
• 1st law of thermodynamics for open systems, including volume work.
• Energy balance for open and closed systems.
• Enthalpy, equations of state and specific heat capacity.
• 2nd law of thermodynamics, cycle processes, reversible and irreversible processes.
• Entropy, T-s/P-v/P-h diagrams, isentropic processes, technical work, isentropic efficiency and the Carnot process.
• Phase diagrams, phase shift, cycle processes and cycle processes with phase shift.
• Heat transfer trough convection, conduction and radiation.
• Introduction to turbines, piston engines, pumps, compressors, heat exchangers, heat/work engines and steam power systems.
• Moist air processes.
Learning and teaching approaches
Lectures, problem solving, laboratory work, hand-ins (theoretical and eksperimental) and self-study (5 ECTS).
Experimental project and report (2,5 ECTS).
Learning outcomes
A student who has met the objectives of the course will be able to:
• Explain the fundamental laws of thermodynamics.
• Describe states and processes by thermodynamic parameters.
• Explain common forms of energy
• Use principles of mass and energy conservation.
• Apply different models, expressed by equations (ideal gas equation), tables and diagrams.
• Determine a systems exchange of work and heat with the surroundings.
• Describe the purpose of the most common forms of thermodynamic machines and plants.
• Perform simplifications for a system, and thereby allow for thermodynamic calculations on components and systems.
• Determine key thermodynamic characteristics for systems and components.
• Determine air humidity and describe humidification and dehumidification processes.
Assessment method
A four-hour written examination.
All materials permitted. The grade is based 30% on submissions throughout the course (15% on assignments and 15% on the report) and 70% on the final test.
The mandatory experimental report, must be passed, to be eligible for the examination and reexamination.
