Learning Objectives
The course is meant to provide the student with an in-depth analysis on different topics related to Energy Engineering, like components design through advanced thermo-fluid-dynamics aspects and energy systems characterization, in the form of energy storage systems. The goal is to provide the student with the knowledge and the methodologies necessary to face and solve, in a proper way, problems related to the treated aspects.
In accordance with the set of KNOWLEDGE AND COMPETENCES developed by the CDS, the knowledge provided during the course are:
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.
In accordance with the APPLICATION CAPACITIES (in accordance with the Dublin Descriptors), the application capabilities provided during the course are:
[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.
