Thermodynamics

Mechanics, Mathematics 1

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.

Thermodynamic states and parameters. Heat and work. 1st law of thermodynamics for closed systems. Energy balance for open and closed systems. Enthalpy, equations of state and specific heat capacity. 1st law of thermodynamics for open systems, including volume work. 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 conduction or radiation. Introduction to turbines, piston engines, pumps, compressors, heat exchangers, heat/work engines and steam power systems

Lectures, problem solving and self-study.

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 different sorts 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 characteristics for a system e.g. efficiency

A four-hour written examination. Reference material permitted. The grade is based 20% on submissions throughout the course and 80% on the final test.
