OVERVIEW

The course deals with the practical and experimental counterpart of some of the theoretical knowledges provided by other courses in the Energy Engineering curriculum.

Energy Laboratory is intended at giving to the students the possibility to touch with their own hands some of the topics related with energy conversion processes and, in particular, with one of them being still particularly significant in the modern world, the combustion.

Besides this, the course is also aimed at giving the students knowledges about the application of the experimental methods that can be extended at a wide variety of different scenarios.

AIMS AND CONTENT

LEARNING OUTCOMES

Acquisition of the theoretical, technical, methodological and practical skills necessary for the experimental investigation of combustive processes. Acquisition of the theoretical basis of the modern measurements and diagnostic techniques applicable to the combustion field as well as of operative skills in utilizing an experimental infrastructure and the measurement techniques theoretically introduced, taking advantage of the equipment present at the Savona Campus. The course foresees also the realization of a simple combustor project and its characterization by means of the most proper experimental techniques.

AIMS AND LEARNING OUTCOMES

Provided that the object of interest of the experimental analysis' is different from one year to another, the students will always have to become familiar with the following experimental activities (steps):

• Individuation of the proper procedure aimed at characterising the experimental rig (namely the wind tunnel plus the selected object of the experimental investigations) and execution of its characterisation.
• Determination of the proper scaled testing conditions (also selecting the most proper similarity criteria to be applied).
• Application of experimental techniques (e.g., hot wire anemometry, pressure acquisition by piezoelectric pressure transducers, etc.) aimed at providing information about the general features of the investigated motion flow field (dynamic characterisation of the motion flow field identifying the possible presence of periodical oscillations).
• Application of experimental methodologies (e.g., Laser Doppler Velocimetry, Phase Doppler Anemometry, Particle Image Velocimetry) aimed at building up a detailed picture of the investigated fluid-dynamic phenomena.
• Application of experimental methodologies (e.g., Chemiluminescence measurements, Laser Induced Fluorescence, Rayleigh thermometry) aimed at building up a detailed picture of involved combustion processes.

Following each of the previous experimental activities, raw data will be collected by the students who will have to apply to them several post-processing techniques following the teacher instructions.

TEACHING METHODS

Classroom frontal lectures introducing to the theorethical aspects related to the experimental methods

Laboratory lectures during which the students, under the theacher supervision, will have to set up and carry out the required experimental activities and, finally, collect the experimental data. 

In order the students can safely and profitably attend the laboratory lectures, these will be held with small (maximum 5-6 people) groups of students.

Collected data will be post processed by the students and presented in a report.

In the case of an extention of the sanitary emergency due to COVID-19, the frontal lectures will be held telematically by means of the Microsoft Teams platform. The laboratory activity will be carried out by the theacher who will produce video tutotrials made, afterwords, available to the students taking advantage, again, of the Microsoft Teams platform. The raw experiemntal data will be, finally, provided to the stuidents in order to be postoprocessed.

EXAMS

EXAM DESCRIPTION

Oral, based on the presentation of the e experimental activities outcomes.

ASSESSMENT METHODS

The students, during the presentation and a following open discussion with the teacher, have to demonstrate, also in the light of the preliminary theoretical subject introduced at the beginning of the course, they master the basics of the utilized experimental techniques setting-up and the data acquisition processes, they have autonomously (following the teacher general instructions) properly postprocessed the experimental data, obtained by their laboratory activities, and, finally, they have been able (again following the teacher general outlining of the physical phenomena the students have been dealing with during the laboratory experiences) to correctly interpret the postprocessed data meaning.
