Topics

• Energy transfer: first and second laws, ideal gases and pure substances, entropy LO1, LO5
• Thermodynamics of energy conversion components and devices LO1, LO4
• Gas and steam power cycles: Carnot, Rankine (ideal and actual), Otto, Diesel, Brayton, regeneration LO2–3
• Reversed heat engines: refrigeration cycles, practical refrigerators and heat pumps, COP LO2–3

Learning outcomes (exam covers LO1–5)

1. Describe how energy conversion devices work and the thermodynamics behind them
2. Solve problems on perfect (Carnot), ideal (Rankine, Otto, refrigeration) and actual cycles
3. Estimate thermal efficiency of power systems and coefficient of performance of refrigeration systems
4. Weigh the environmental and economic cost of energy input against useful output
5. Analyse problems on the rational use of energy
6. Carry out lab work in a group and analyse the data
7. Write up and interpret measurements in a lab report
8. Present a team investigation to an audience
