COMPLEMENTI DI MACCHINE E SISTEMI CONVERTITORI DI ENERGIA
(objectives)
EDUCATIONAL OBJECTIVES: The course aims to provide students with the knowledge necessary for the design and verification of fluid machines and energy systems of different types, integrating the basic knowledge typically achieved in the industrial engineering degree at the Batchelor level (off-project heat exchangers, driving and operating volumetric machines, gas turbines with blade cooling and gas micro-turbines, combined systems at multiple pressure levels, fuel cells).
EXPECTED LEARNING RESULTS: At the end of the course the student is expected to have the following knowledge: - knowledge of the detailed operation of heat exchangers, gas turbines with blade cooling and micro-gas turbines, combined systems at multiple pressure levels, fuel cells, fuel processing systems for the production of syngas with a high hydrogen content; - knowledge of the configuration, of the operating principles and of the selection criteria of the main types of volumetric fluid machines. At the end of the course the student is expected to have the following skills: - ability to design thermal engine systems and volumetric machines of medium and high complexity; - ability to check volumetric machines, gas turbines, combined systems at multiple pressure levels, thermal engine systems, hydraulic motors and refrigerators in different operating conditions; - ability to choose a volumetric machine according to the field of application; - ability to carry out the sizing of volumetric pumps and compressors and internal combustion engines; - ability to carry out the dimensioning of fuel processing systems for the production of syngas with a high hydrogen content and of different types of fuel cells; - ability to operate correctly (power regulation, control of operating parameters, performance monitoring) volumetric machines, gas turbines with blade cooling and gas micro-turbines, combined systems at multiple pressure levels, fuel cells. At the end of the course the student is expected to have the communication skills to describe, in written and oral form, the sizing, design choices, checks, operations and monitoring in the areas of heat exchangers, gas turbines with cooling of gas blades and microturbines, combined systems at multiple pressure levels, fuel cells, fuel processing systems for the production of syngas with a high hydrogen content.
