Learning Objectives - Last names A-L
The course aims to provide students with the basis for the current assessment, verification and design of energy conversion systems, with particular reference to those most currently used in industrial plants.
Knowing and classifying the main and common energy systems, describing the operating principles of the various components. Execute
evaluations of system performance based on energy balances, taking into account the relative characteristics of machines and fluids. Finally, to be able to identify algorithmic approaches and to use databases to achieve the above training objectives.
With reference to the knowledge (CC) identified for the course, reference is made to the following descriptors:
cc4: Knowledge and understanding of thermodynamics applied to energy systems and of fluid-dynamic phenomena as well as models capable of representing them. Knowledge of systems and machines for the production and conversion of energy, with particular reference to turbomachinery and industrial combustion equipment. Understanding the role of different energy technologies in ensuring the environmental and economic sustainability of production.
cc9:Knowledge and understanding of information technology including the role they play in supporting design. Understanding the organization of information in databases and computer design to support processes.
While in reference to the competences acquired (CA) identified for the Course reference is made to the following descriptors:
ca4: Applying knowledge and understanding related to analytical modelling and experimental methods to design, analyze and test fluid machines, thermal motors and energy conversion systems. This includes: the application of design criteria for technical and thermos-technical plants, fluid and energy distribution; the application of thermodynamic principles to simple systems; the understanding of the main thermodynamic cycles and the reading of thermal diagrams; the identification of significant heat transmission mechanisms for engineering applications; the analysis and functional design of equipment of mechanical interest such as turbomachinery, energy conversion systems and internal combustion engines; the evaluation of the energy, economic and environmental performance of fluid, thermal and oleo-dynamic machinery.

Type of Assessment - Last names A-L
Students can take part in 3 intermediate tests during the course. After passing the intermediate tests, the oral test (single question) and the final vote are directly accessible. If the student does not take part or pass the intermediate tests, the student must pass a written test (very similar to one of the intermediate tests) and the oral test.
The tests are oriented to verify Ca4 skills in close relation to the cc4 objectives. In particular, the written tests assess the ability to select and use suitable mathematical models for the description and performance estimation of thermodynamic cycles and corresponding energy systems, while the oral question is dedicated to the evaluation of the ability to describe energy systems and their components, highlighting their peculiarities and performance characteristics (cc4).
The student must be able to show at least sufficient knowledge of mathematical/physical modelling methods of energy systems of general interest (written test ) and sufficient knowledge of the energy components and systems described in the course (oral test).
N.B. For the cc and ca defintion please see Learming objectives section.

Type of Assessment - Part B
The student can take part in 2 intermediate tests during the year.
After passing the intermediate tests, the oral test (two questions) and the
final vote are directly accessible. If the student does not take part or pass the
intermediate tests, during the oral test a solution of an additional exercise will be requested.
The tests are oriented to verify Ca4 skills, in close relationship
with cc4 objectives.
In particular, the written tests and additional exercises evaluate the ability to select and use appropriate mathematical models for describing and estimating the performance of thermodynamic cycles and corresponding energy systems,
the oral test is instead dedicated to evaluating the ability to describe energy systems and their components highlighting their characteristics and performance with particular attention to applications that include electrical and electronic equipment.
The student must be able to show a at least sufficient knowledge of modelling methods mathematics/physics of energy systems of general interest (written test or exercises) and sufficient knowledge of the energy components and systems described in the course (oral test)
