The lectures are focused on developing the knowledge required to analyse energy cycles performance (e.g. efficiency, power output, work and heat input) from cycle data. Steam Power (Rankine) Cycle: beginning with a simple cycle and adding more refinements (feedheating, economiser etc.). Application to electrical power generation where the heat source is supplied by: i) fossil fuel and ii) nuclear fuel. Gas Turbine (Brayton) Cycle: simple, then add intercooler, heat exchanger and reheater. The use of gas turbines for gas turbines to electrical power generation. Latest developments with concentrated solar energy as a heat source. Cooling towers. Hybrid systems: CHP, steam turbine with gas turbine. Exergy analysis of the energy cycles.
