OVERVIEW

The course deals with the most relevant topics relating to internal combustion engines for the automotive field, to turbomachines for energy generation and aeronautical propulsion systems and to energy conversion plants.

AIMS AND CONTENT

LEARNING OUTCOMES

The course presents operational and functional concepts on internal combustion engines for the automotive field, on aeronautical engines (air propulsion systems) and on energy conversion plants. Moreover, the main numerical and experimental techniques for analysis of machines and energy systems will be presented.

AIMS AND LEARNING OUTCOMES

The student attendance during the lessons and related study activities will allow:

- to know the main features related to experimental investigations on internal combustion engines;

- to know the main features related to experimental investigations on turbocharging systems;

- to identify the main features of the turbomachines used in the different application areas;

- to know the architecture of the main types of aeronautical propulsion systems;

- to evaluate the performance of turbomachines;

- to know the basic aspects of emissions and related abatement, renewable source applications, and distributed generation (considering also cogeneration and trigeneration);

- to apply the thermodynamic knowledge to the performance calculation of energy systems (also with a software).


 

PREREQUISITES

It is required that the student has acquired sufficient knowledge of the basic aspects related to fluid machines and energy systems.

TEACHING METHODS

Lectures on the different items presented in the course programme and experimental activities on different test rigs, focusing on specific arguments developed within the course. Moreover, seminars offered by academic and industrial experts and technical visits can be organised.
Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it), the Polytechnic School's disability liaison.

EXAM DESCRIPTION

Examination: oral test.

Students with a certified learning disability (DSA), a disability, or other special educational needs are invited to contact the instructor at the beginning of the course to discuss teaching and examination arrangements that, while respecting the learning objectives of the course, take individual learning needs into account and provide appropriate accommodations.
Please also note that requests for exam accommodations or exemptions must be submitted using the form available at this link 
https://modulionline.unige.it/richiesta-adattamenti#no-back , to the course professor, the DIME contact person (federico.scarpa@unige.it), and the relevant office (inclusione.studenti@info.unige.it) at least seven working days before the examination, in accordance with the guidelines available at this link 
https://unige.it/disabilita-dsa/richiesta-servizi

ASSESSMENT METHODS

The oral examination consists of three questions, each focusing on one of the main macro-areas of the course. The interview will cover the topics addressed during lectures and aims to assess not only the depth of the student's knowledge, but also their analytical skills and critical thinking. The final grade will also take into account clarity of expression, the appropriate use of technical terminology, and active participation in the course activities.
