AIMS AND CONTENT

LEARNING OUTCOMES

The course provides an updated picture of traditional and innovative energy production plants with particular regard to the reduction of polluting emissions and the increase of conversion efficiency

AIMS AND LEARNING OUTCOMES

The attendance and active participation at the proposed teaching activities (lessons and exercises) and the individual study will allow the student to:

- know the topics related to combustion and pollution formation;

- know the characteristics of boilers and advanced aspects of mixed cycles;

- apply the thermodynamic concepts to the performance calculations;

- analyse and calculate energy system performance (group-based activities will be carried out);

- know the basic concepts on wind generators;

- know the basic concepts on alternative internal combustion engines;

- identify and analyse the main plant components.

In particular, thanks to the participation in the planned educational activities, it will be possible to obtain the following skills:

- ability to identify own abilities, ability to concentrate and critically reflect on a task (personal competence);

- ability to manage own social interactions, collaborative attitude, constructive communication in different environments (social competence);

- awareness of preferred learning strategies, organization and evaluation of personal learning according to what is understood and learned (ability to learn to learn).

TEACHING METHODS

The course will be composed of lectures, laboratory visits and numerical exercises (for a total amount of 60 hours). The hours dedicated to the exercises will be carried out by the professors in charge of the course in the following way: summary introduction of the contents carried out in the lectures and development of exercises on the main topics. Attendance at all the proposed educational activities is strongly recommended. In detail, participation at numerical exercises is important to acquire the skills necessary for the development of the exam report.

EXAMS

EXAM DESCRIPTION

Assessment of the exercise reports (group-based activities).

ASSESSMENT METHODS

The reports related to the exercises will be produced with group working activities, before the classroom activity termination (the deadline will be provided by the teachers during the assignment). These reports will be evaluated producing an x/30 mark and this will the exam evaluation.

The details on the exam preparation and on the analysis of each topic will be provided during the lessons. The exam will evaluate not only the student's knowledge, but also the analysis capability of problems on the course program and the presentation with a right terminology.

FURTHER INFORMATION

Students with specific needs (for instance Specific Learning Disorders) are invited to contact the teachers by e-mail (mario.ferrari@unige.it, stefano.barberis@unige.it and silvia.marelli@unige.it) at least 5 days before the exam. For instance, students with learning disorders ("disturbi specifici di apprendimento", DSA) (certified by related medical documentation) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.
