Course Aims
The aims of this course are to:
■ provide an introduction to the 2nd Law of Thermodynamics and its corollaries, including the concepts of the Heat Engine, Entropy, and Availability
■ provide an introduction to the vapour compression refrigeration / heat pump cycle, and Rankine power cycle
■ introduce key elements of perfect gas theory for propulsion, including speed of sound, Mach number, propulsive force, stagnation temperature and pressure
■ provide an introduction to gas turbine cycle analysis, including gas turbine components (intake, gas generator, nozzle) and the turbo-jet cycle.
Intended Learning Outcomes of Course
By the end of this course students will be able to:
■ perform a complex engineering system calculation completely and accurately;
■ demonstrate the importance and implications of the Second Law of Thermodynamics by using the Kelvin-Planck and Clausius statements, along with simple associated thermodynamic models, such as heat reservoirs, heat engines, and heat pumps;
■ explain the concept of entropy and why the total entropy present in the universe will only ever increase;
■ determine the entropy change of open and closed systems undergoing typical thermodynamics processes, such as a phase change, heat transfer, work transfer, compression, and expansion;
■ evaluate the environmental and societal impact of solutions to complex thermodynamics problems.
■ apply the principles of reversible and irreversible processes and the steady flow energy equation analyse thermodynamic cycles, e.g., the refrigeration cycle;
■ develop a code for solving the Rankine cycle, drawing conclusions about the cycle efficiency and consider the ethical and security issues when this cycle is applied to the nuclear power industry;
■ analyse the turbojet, turboprop, and turbofan cycles; develop an understanding of why different engines are more efficient for different flight regimes.
Minimum Requirement for Award of Credits
Students must attend the degree examination and submit at least 75% by weight of the other components of the course's summative assessment.
Students must attend the timetabled laboratory classes.
Students should attend at least 75% of the timetabled classes of the course.
Note that these are minimum requirements: good students will achieve far higher participation/submission rates. Any student who misses an assessment or a significant number of classes because of illness or other good cause should report this by completing a MyCampus absence report
