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).


 

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.

SYLLABUS/CONTENT

Experimental investigation on reciprocating Internal Combustion Engine (ICE): measuring equipment, test facility set-up, ICE installation on dynamometer test bench, evaluation of engine performance, fuel consumption, ICE pollutant emissions. Experimental definition of automotive turbocharger performance. Experience at the Internal Combustion Engine Laboratory of DIME Department.

Turbomachines for energy and aeronautical propulsion – Types of turbomachines and application fields; performance parameters; work exchanged between machine and fluid; loss sources and correlations. Turbomachines for energy production. Turbomachines for aeronautical propulsion: propulsion system architectures (turbojet, turbofan and turboprop). Experimental techniques for turbomachinery applications. Laboratory experience: experimental investigation of the aerodynamic performance of a blade cascade, using facilities and instrumentations of the Aerodynamics and Turbomachinery Laboratory of the DIME Department.

Environmental impact of energy systems. Renewable energy sources: plant typologies. Distributed generation: basic aspects, plant typologies, and applications. Co-generation and tri-generation: applications of these technologies with the main energy systems. Calculation of thermodynamic balances and performance parameters for plants with the W-TEMP software: operative practice.
