CODE 80377 ACADEMIC YEAR 2021/2022 CREDITS 6 cfu anno 2 INGEGNERIA MECCANICA - ENERGIA E PRODUZIONE 10800 (L-9) - SAVONA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/08 LANGUAGE Italian TEACHING LOCATION SAVONA SEMESTER 2° Semester MODULES Questo insegnamento è un modulo di: APPLIED PHYSICS AND FLUID MACHINERY TEACHING MATERIALS AULAWEB OVERVIEW The module provides the students with the fundamental skills to interpret the processes, as well as the technologies, related to fluid machines, thermal machines and energy conversion systems. This allows the student to master the basic principles of thermodynamics and fluid dynamics when applied to the design and the analysis of energy conversion equipment, as well as to address the functional behavior of fluid machines both in themselves and when components of power systems. AIMS AND CONTENT LEARNING OUTCOMES The course provides the skills to interpret the functional processes, and the basic design configurations, related to Energy Conversion Machines (ECM), i.e. fluid machines, thermal machines and power plants AIMS AND LEARNING OUTCOMES At the end of the course the student should achieve a basic knowledge about the operation of positive displacement and dynamic fluid machines and be able to evaluate the main performance aspects. TEACHING METHODS The course is organized in lectures and exercises. SYLLABUS/CONTENT A. Positive displacement fluid machines - Introductory concepts Classification of fluid machines. The energy equation and the expression of work. Conversion efficiency in fluid machinery. Work exchange in the positive displacement fluid machines . - Reciprocating internal combustion engines (ICE) Historical overview and fields of application. Basic knowledge on ICE: classification, components and nomenclature, main operational parameters. Ideal and real operation of 2 and 4 stroke engines. Indicated diagrams, indicated and brake mean effective pressure, engine power correlations. Reference thermodynamic cycles for spark ignition (SI) and diesel engines. Regular and abnormal combustion processes in ICE. Part load operation of SI and diesel engines. ICE performance curves. Supercharging and turbocharging: basic plants design, application fields, operational issues, thermodynamic cycles, compressor and turbine power. ICE pollutant emissions: influence of combustion process and operational engine parameters on exhaust emissions, emission control systems and aftertreatment devices for SI and diesel engines. - Positive displacement compressors and pumps Reciprocating displacement compressors: operating principle, constructive characteristics, ideal and real working cycle, flow rate control systems. Rotary displacement compressors: vane, lobe, liquid ring, screw compressors. Volumetric pumps: alternative and rotary machines, working principle, construction types. Characteristic curves. Fluid machine-circuit matching. RECOMMENDED READING/BIBLIOGRAPHY M. Capobianco - “Macchine volumetriche” – Appunti del corso. R. Della Volpe - “Macchine” - Liguori Editore, 2011. V. Dossena, G.
