Engineering Thermodynamics

Concepts and definitions; the thermodynamic system, properties, phase equilibrium of pure substances, equations of state for gases, tables of thermodynamic properties, work and heat. First law of thermodynamics; thermodynamic cycles, change of state, internal energy, enthalpy, specific heat; open systems, steady-state and transient processes. Second law of thermodynamics; reversible and irreversible processes, the Carnot cycle, the thermodynamic temperature scale, entropy, the entropy production concept. Thermodynamic power cycles, including Rankine cycle, Otto cycle, Diesel cycle, Brayton cycle, Ericsson cycle and Stirling cycle. Introduction to compressible flow. Refrigeration and heat pump systems.

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. - Ideal gas model, its assumptions, applications and limitations. - Different cyclic processes such as Carnot, Rankine, Otto, Diesel and Brayton. - Compressible flow. – 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 energy efficiency of processes. - Overview of processes for power production, heating (heat pumps) and cooling (refrigeration cycles).

Lectures. Weekly assignments. One Python project assignment during the semester.
