    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.

    Turbomachines for energy and aeronautical propulsion - Types of turbomachines and application fields. Turbomachines for aeronautical propulsion: the architecture of the main propulsion systems (turbojet, turbofan and turboprop). Performance parameters of a turbomachine; loss sources and correlations. Experimental techniques and facilities for the study of flow in turbomachines. 4-hole pneumatic probe: calibration and use for measuring the profile losses of a cascade.

    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.

    EXAM DESCRIPTION

    Examination: oral test. At first exam session, it will be offered the opportunity to take the exam also in written test, if the Covid19 allows to attend the exam face to face.

    Students with SLD, with disabilities, or with other regularly certified special educational needs will agree with the teacher on the exam method and the compensatory instruments, by contacting the instructor at least 10 days before the exam. They will also be able to take advantage of the additional time required by law.

    ASSESSMENT METHODS

    The oral examination will be focused on the topics treated during the lessons and will be aimed at evaluating not only the fulfilment of an adequate knowledge level, but also the acquisition of critical analysis skills on the topics of the exam.
