Syllabus
Prerequisites: General knowledge of Applied Thermodynamics and Heat transfer.
Target skills and knowledge: Basic principles of energy conversion in different types of fluid machines and energy systems such as hydraulic turbines and hydroelectric plants, steam turbines and steam power plants, gas turbines; application areas of the different types of fluid machines and power plants, criteria for their selection; preliminary design procedures.
Examination methods: The exam consists of two compulsory and sequential activities:
- preliminary design of a fluid machinery;
- oral exam.
The preliminary design of a fluid machinery, to be carried out as homeworks during the course, involves the preparation of a technical report and the execution of technical drawings of machine components, to carry out individually, although the student can cooperate within a team consisting of no more than 3-4 students.
The preliminary design contributes about 30% of the final grade, while the remaining 70% is given by the oral examination.
The oral exam typically involves three questions about the entire course syllabus, and takes about 45 minutes.
The oral examination is done in Italian.
Assessment criteria: Fluid machinery preliminary design:
- the correctness of the general approach;
- the accuracy of the methodology for calculating and verifying the results;
- the appropriateness of the technical terminology adopted;
- the overall quality of the proposed fluid machinery preliminary design.
Oral exam:
- knowledge and understanding of the teaching course contents;
- ability to describe the fluid machinery fundamental principles and performance;
- criteria for selecting proper types of fluid machinery and energy conversion system configuration;
- simple problems of preliminary sizing of fluid machinery components;
- ability to discuss the topics in a clear and concise way, with a proper use of technical terminology;
- time elapsed from the end of the classes and the date of the oral exam
Course unit contents: Hydroelectric and steam power plants: present situation and future perspectives.
Hydroelectric plants: site section and basic layout, evaluation of the water resource and economic evaluation of the project.
Pelton turbines: general features, runner and jet diameters, number of blades, relative path of the jet, blade geometry, nozzle and needle profiles, preliminary projects.
Francis Turbines and Propeller and Kaplan turbines: geometrical configurations, runner geometry, distributor and spiral casing, draft tube, preliminary projects.
Steam power plants: schemes and thermodynamic cycles; effects of the vaporization pressure, condensation pressure, superheating, reheating and regenerative heating on the cycle efficiency; application exercises.
Steam turbines: impulse stage a reaction stage; de Laval, Rateau, Parsons and Curtis turbines; steam turbine configurations; criteria for maximum efficiency in a steam turbine stage, load regulation; application exercises.
Gas turbines: schemes, thermodynamic cycles, energy balances; application exercises.
Cogeneration and combined cycle plants; application exercises.
Planned learning activities and teaching methods: Traditional teaching methods complemented by laboratory practices.
Application areas of different types of fluid machines and energy systems; criteria for their selection; design procedures and preliminary design examples.
