OVERVIEW

The course aims to broaden and deepen the 'machinery' knowledge inherent in the teaching of machines of the Bachelor's Degree Course in Naval Engineering, in order to adapt them to the level required in the Master's Degree.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to broaden and deepen the 'machinery' knowledge inherent in the teaching of machines of the Bachelor's Degree Course in Naval Engineering, in order to adapt them to the level required in the Master's Degree.

AIMS AND LEARNING OUTCOMES

he notions provided in the course go beyond the mere explanation of the functional aspects, as they allow understanding, in principle, of the sequences and procedures for choosing, designing and optimizing machines. Some issues, such as: combined and cogeneration plants, reduction of emissions from naval plants, use of hydrogen as an energy vector and electric propulsion, not covered in the Machine Course (Bachelor's Degree), complete the student's training and knowledges.

TEACHING METHODS

Theoretical lessons.

SYLLABUS/CONTENT

Thermodynamic fundamental principles review: main thermodynamics and energy equations, stagnation thermodynamics quantities, Mach number.

One-dimensional theory of the compressible-fluid flow: subsonic and supersonic flow, Hugoniot equation, de Laval nozzle theory (de Saint Venant equations, Stodola’s cone).

Turbo-machines theory: stage reaction degree, axial turbine stages optimization, radial compressor theory.

Gas turbine plants: combustion chamber polluting emissions and them limitation techniques.

Combined and cogeneration plants: Definition and classification of combined plants, main typologies, combined gas-steam plants, cogeneration plants. Examples of naval application.

Efficiency improvement and emission reduction of naval plants: Main regulations on the emissions of naval plants, the "natural gas" as an alternative fuel to the traditional liquid naval fuels, examples of studies of "energy efficiency" and emission reduction of two existing ships. Economic analysis of naval installations.

Hydrogen as energy carrier: The role of hydrogen in energy and environmental sustainability. Operating principles of fuel cells and main features. Electric propulsion and its impact on the environment.
