OVERVIEW

The course is aimed at students of Naval Engineering at the Polytechnic School of the University of Genoa. The course aims to provide information on the machines used on board vessels (engines: internal combustion engines, gas turbines, steam plants; operating machines: compressors and fans, pumps).

AIMS AND CONTENT

LEARNING OUTCOMES

To give the student a knowledge regarding the typology and physical running principles regarding the energy conversion machinery (i.e.: engines, turbines, compressors, pumps), employed on the ships.

AIMS AND LEARNING OUTCOMES

At the end of the course the student will be able to:

- know the  conformation and operating principles;

- perform numerical calculations to determine the functional characteristics and performance parameters of the machines;

- choose the most suitable machine and its correct use.

PREREQUISITES

The basic knowledge necessary to understand the topics covered in the course concern the following subjects: Mathematics, Geometry, Physics, Chemistry, Thermodynamics.

TEACHING METHODS

Theoretical lessons and exercises.

GenovaStudents with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's contact person for disability at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns. Contacts of the School's disability contact person can be found at the following link: Comitato di Ateneo per l’inclusione delle studentesse e degli studenti con disabilità o con DSA | UniGe | Università di Genova
