Objectives

In accordance with the objectives of the Master's Degree in Mechanical Engineering, the specific objectives of the course are to provide the student with skills related to the environmental impact of the energy systems as a whole and to provide the main knowledge about the technologies for controlling the environmental impact of energy systems. The course provides the main knowledge and methodological procedures based on environmental impact studies in the field of energy production plants of industrial interest, with particular reference to steam plants, gas turbines, gasification plants, wind plants, biomass plants, etc.

The main expected learning outcomes from the course of Environmental Impact of Energy Systems, according to the 5 Dublin Descriptors, are as follows:

Knowledge and understanding skills
• Acquire basic knowledge about the main forms of environmental pollution from energy systems (atmospheric, thermal, acoustic, etc.)
• Understand the principles of formation of the main atmospheric pollutants.
• Acquire the basic knowledge about the main monitoring technologies of environmental impact from energy systems.
• Acquire the knowledge about the dispersion of pollutants into the atmosphere.

Ability to apply knowkedge
• Acquire the ability to assess the effects on the environment of the main forms of pollution (atmospheric, acoustic, water, etc.).
• Acquire the ability to assess atmospheric pollution generated by any energy system.
• Acquire the ability to design the main pollutant removal systems.

Autonomy of Judgment
• Acquire the ability to evaluate the level of pollution produced by a particular energy system in order to carry out qualitative and quantitative comparisons and qualitative assessments between the various pollutant removal technologies.
• Acquire the ability to recognize system solutions of different sizes, types, and configurations for removal systems, to estimate the value of the different performance indices related to the above characteristics, and to carry out qualitative and quantitative comparative analyzes and evaluation about energy and environmental plan.

Communication Skills
• Acquire the ability to prepare a technical report in which the assumptions and the main results are reported and discussed.

Ability to learn
• Acquire the ability to integrate knowledge related to other courses to achieve a broad knowledge in the field of energy conversion systems. In addition, the course will help to pursue PhD or master's degree courses and to continue professionally updating at an individual level.

Teaching Methods

The course lasts 60 hours. The teaching will be delivered simultaneously both in presence and online, thus outlining a mixed teaching that can be enjoyed at the university classrooms, but at the same time also at a distance. At the beginning of the semester, each student can opt for face-to-face or distance teaching. Depending on the availability of the classrooms and the number of students who will opt for the attendance mode, there may be a shift for actual classroom access. The lessons take place mainly in the traditional way through the use of the blackboard or through the slide show. Practical consist in carrying out problems of sizing and performance evaluation of different pollutant removal plants.

Verification of learning

The final exam is composed of a test plus an oral exam. In the 3-hour test, problems about mass and energy balance are typically proposed together with problems of rating and performance testing of different pollutant removal systems. Moreover, one or two theoretical questions are proposed.
The oral exam consists of a discussion about some of the topics proposed in the classroom during the course, together with insights into the characteristics and performance of the various removal technologies.
Voting of the test is weighted by the vote attributed to the individual problems and questions based on their complexity. The 18/30 vote is given when the knowledge/skills highlighted in solving problems are at least elementary, the evaluation of 30/30 as the knowledge is excellent. For the evaluation of the test, the score takes into account the following elements: a) Adequacy of the resolution procedure; b) Adequacy of the assumptions; c) Correctness of the calculations.
For the oral: the 18/30 score is given when the knowledge/skills highlighted are at least elementary, the score of 30/30 as the knowledge is excellent. The evaluation of the score takes into account the following elements: a) correctness and completeness of the answers, b) capacity of problem analysis, c) language properties, d) clarity of exposure. The items referred to points (a) and (b) constitute a mandatory condition to pass the oral test.
