TEACHING METHODS Classroom lessons (48 hours) and exercises (12 hours). SYLLABUS/CONTENT Worldwide and Italian energy demand and the energy sources. Machine classifications. Fossil (and renewable) fuels; the combustion; stoichiometric air; air excess. Thermodynamic aspects: T,S and H,S charts, Carnot's cycle and its efficiency. Efficiency parameters: ideal, limit and real cycles; adiabatic and polytropic efficiency; global efficiency and auxiliary impact. Steam cycles and related plants: efficiency; methods to increase steam cycle efficiency; regeneration; thermal balance; circuit general aspects; main components. Regulation of steam turbines and aspects on nuclear power plants. Gas cycles: turbogas technology; ideal, limit and real cycles for the simple layout; ideal cycle efficiency; maximum useful work; efficiency of limit and real cycles. Work-Efficiency chart; heavy-duty and aereoderivative turbines; the main turbogas components; the recuperated cycle (ideal and real) and its performance; intercooled cycle (ideal and real); reheated cycle (ideal and real). Aspects on aeronautic gas turbines. Combined cycles: aspects on combined cycle types; the recovery steam generator (one pressure level), the pinch-point and subcooling values; the optimal vaporization pressure for a one pressure level; combined cycle efficiency. The internal combustion engines (ICEs): basic aspects and classification; geometry parameters; working cycles for two and four strokes; ideal cycles and their efficiency; comparison between the cycles; limit and real cycles; the indicated cycle; aspects related to the engine/user coupling; the ICE regulation; ICE emissions; supercharging.
