LEARNING OUTCOMES: The course aims to provide students with the basic principles, physical laws, and applications of thermodynamics, thermo-fluid dynamics and heat transfer, with the dual purpose of preparing them to afford more applicative courses, and use the acquired knowledge for design and sizing simple components and thermal systems.


Students will have to understand the physical laws of applied thermodynamics and heat transfer, and understand the structure and operation of the simplest components and systems. They will also demonstrate that they have acquired the basic methodologies for verifying and designing the studied devices.


Students must be able to afford courses for which this course is preparatory (for example Thermotechnique, or Machines) and to size or verify simple components and systems, topics covered by the course, such as air conditioning systems, engine systems, fins and heat exchangers.


Students must assume the autonomous capacity to face the subsequent studies for which this course is preparatory and to draw up simple projects of thermal systems that use the studied components. They will also need to be able to evaluate projects written by other parties, checking that the project requirements are satisfied.


Students must be able to illustrate in a complete and exhaustive way the acquired information, the results of their study and of their project activity, also through the normally used means of communication (discussion of the results obtained, report on the performed activity, PowerPoint presentations, etc.).


Students must be able to apply the physical laws underlying the studied phenomena, and to face further studies that use the acquired knowledge. They will have to be able to expand the already owned information through the analysis of technical-scientific literature and to modify their curricula choosing future knowledge to be acquired on the base of their knowledge and tendency.
