Academic Year 2023/2024 - Teacher: Rosario LANZAFAME

Expected Learning Outcomes

The "Energy Systems and Environment" course deals with the very current problem related to the development of sustainable energy systems for the decarbonized production of electric, thermal and freezer energy. In particular will be analysed the resources of energy used, their origin, the conversion process and all the final use of energy in the various forms, with a view to achieving environmental sustainability inserted in the global planetary context. The scenarios of the environmental crisis of the 21st century will be considered.

The various energy sources will be presented including biomass energy, geothermal energy, wind energy, solar energy, the hydrogen vector and the characteristics of the respective generation systems. Particular attention will be reserved to the analysis of energy technological systems in the context of environmental respect objectives, first of all, the control of the production of climate-changing gases, in order to achieve mitigation effects on the phenomenon of "Global Warming".

Computational Fluid Dynamic techniques for the simulation of Energy Systems will be presented. Specifically the students will learn how to implement numerical CFD simulations through Ansys Fluent software with both a theoretical and a practical approach.

In the final part of the course the advanced energy systems will be mentioned, with particular attention to combined cycle gas and cogeneration power plants and their integration with solar thermal energy capture systems.
