CODE 66172 ACADEMIC YEAR 2020/2021 CREDITS 6 cfu anno 3 INGEGNERIA MECCANICA 8720 (L-9) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/08 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 2° Semester TEACHING MATERIALS AULAWEB 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. RECOMMENDED READING/BIBLIOGRAPHY Lesson notes and classroom material (which can be downloaded in aulaweb) are sufficient for the exam preparation. S.
