051113 - FUNDAMENTALS OF ENERGY TECHNOLOGIES
The course aims to provide the students with the theoretical knowledge of physics and engineering to understand, model and design different technologies, ranging from traditional energy conversion systems to electrochemical devices, like batteries and fuel cells, that occupy a growing role in energy conversion and storage sector.
The course fits into the overall program curriculum pursuing some of the defined general learning goals. In particular, the course contributes to the development of the following capabilities:
Understand context, functions, processes in energy technologies and the impact of those factors on energy technologies development
Design solutions applying a scientific and engineering approach (Analysis, Learning, Reasoning, and Modeling capability deriving from a solid and rigorous multidisciplinary background) to face problems and opportunities in energy technologies
Risultati di apprendimento attesi
The main expected learning outcomes consist in:
Identify the physical processes regulating and limiting the operation of conventional and electrochemical energy technologies
Point out requirements of energy technologies in function of different applications
Identify and understand the main technological issues regarding electrochemical devices and their impact on technology development and costs
Determine performance and efficiency of conventional and electrochemical energy technologies in different operating conditions
Calculate efficiency losses occurring in physical processes of energy technologies and assess room for improvement
Design energy technologies for both stationary and automotive applications, focusing on the trade-off between performance and cost
The course provides the basis of thermodynamics to deal with the design criteria of different energy technologies. Then, after a technological assessment, the features of some traditional and electrochemical conversion and storage systems for automotive and stationary applications are analyzed in depth, focusing on performance, efficiency, technological issues and off-design conditions.
