OVERVIEW

The teaching unit describes the energy and propulsion systems based on fluid machinery. Power generation systems based on steam or gas turbines are discussed with attention focused on thermodynamic cycles and strategies to improve the energy conversion efficiency. The fluid machinery are then presented and discussed together with their operating principles and their design parameters.Volumetric fluid machinery and turbomachinery are described.

AIMS AND CONTENT

LEARNING OUTCOMES

The module provides the students with the fundamental skills to interpret the processes, as well as the technologies, related to fluid machines, thermal machines and energy conversion systems. This allows the student to master the basic principles of thermodynamics and fluid dynamics when applied to the design and the analysis of energy conversion equipment, as well as to address the functional behavior of fluid machines.

AIMS AND LEARNING OUTCOMES

The student will be able to select the most appropriate fluid machine to install in a given plant layout. The knowledge of the flow physics and structures inside the fluid machinery will allow the student to understand in some detail the operation of the machine and to support him/her in trouble shooting in case of non conformal operation.

The course provides the required theoretical concepts and competences required by Functions 1,2,3,4, from Table A-III/1 and A-III/2 in Convention STCW (marine engineer).

In particular will be provided the basic construction and operation principles of machinery systems, including:

.1 marine diesel engine
.2 marine steam turbine
.3 marine gas turbine
.4 marine boiler
.6 other auxiliaries, (including various pumps, air compressor, heat exchanger)

Moreover, will be provided also the design features, and operative mechanism of the previous machinery and associated auxiliares.

The course contributes to the empower the student with soft skills especially related to the alphabetic-functional competence.

PREREQUISITES

Basic and applied thermodynamics are pre requisites to support at best the understanding of the physical and technical aspects in the present course.

TEACHING METHODS

Teoretical lessons with numerical application exercises

Working students and students with certified SLD (Specific Learning Disorders), disability or other special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and examination arrangements so to take into account individual learning patterns, while respecting the teaching objectives.

SYLLABUS/CONTENT

Gas turbines and steam plants for energy producion or propulsion. Basic principles of fuel cells. Internal combustion engines. Volumetric compressors and pumps. Turbomachinery (axial and radial turbines and compressors).

The course contributes to one or more of the following specific goals (Obiettivi di Sviluppo Sostenibile) from Agenda ONU 2030:

- Objective 4: guarantee an eductaion of quality, equal and inclusive, and opportunity of learning for anyone

- Objective 5: get the gender equity and support women and girls in their learning process

- Objective 14: save and use the oceans, seas and marine ressources in the best way for a sustainable development

The course contributes to empower the student with soft skills especially for alphabetic-functional competences.

EXAMS

EXAM DESCRIPTION

Oral examination. The exam date can be agreed with the teacher according to the student proposal.

The exam might be online according to the rules from Regolamento di Ateneo.

ASSESSMENT METHODS

The oral exam is aimed at understanding the actual level of knolwledge of the student and her/his capability to pick the most important issues in the operation and functioning of fluid machinery and energy systems.

The oral exam will also be useful to check the proper technical language and the potential or limitations of the models in the specific field of application.
