Conoscenze e abilità da conseguire
Aim of the course is to give the student the fundamental knowledge to plan and execute an experimental campaign in Aero and Fluid-dynamics, as well as the knowledge of the most important instruments and experimental techniques in Aerodynamics. Specifically, at the end of the course the student will be able to: - Determine the relevant variables and non-dimensional parameters for a given fluid-dynamic system; - Choose and/or design the most appropriate experimental setup and measurement instrument - Critically evaluate and analyze the experimental data together with the associated uncertainty"

Metodi didattici
This course will be held with innovative teaching methdos:
The initial part of the course will be conventional lectures held by the teacher where general and theoretical aspects of Experimental Aeordynamics are indroduced and discussed by the teacher in frontal lectures;
The second part of the course will involve "hands-on" laboratory experience at the international research center CICLoPE. Laboratory exercises are sepcifically designed for the students to learn the best practices in experimental aerodynamics and to apply and verify the theoretical background learnt in the lectures.
The final part of the course the students will present the results of the laboratory experience and learn how to write a scientific report.
The course will be complemented with seminars held by international lecurers on advanced experimental and numerical techniques;
Digital material such as recorded lectures and digital lecture notes, as well as other multimedia material will be available on Virtuale platform.
As concerns the teaching methods of this course unit, all students must attend Module 1, 2 online [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas], while Module 3 on health and safety is to be attended in class. Information about Module 3 attendance schedule is available on the website of your degree programme.
Modalità di verifica e valutazione dell'apprendimento
The examination is in the form of an oral test held in the following modality: the student will be asked 2 or 3 questions on the different subjects covered in class (including seminars). For each question, the student will be given some time to wirte down the main points to be discussed with the teacher.
The student is expected to clearly explain all the relevant aspect of the experimental or analysis techniques, including physical principles behind the measurement technique, making clear connections between the mathematical aspects discussed in class and the technical issues connected to the application. Fundamental of Aerodynamics, fluid-dynamics will be treaded as necessary prior knowledge.
Criteria with which the grade will be formed are:
- Demonstrated knowledge of the course content
- Clarity of explanation
- Capability of making connections between theoretical and practical apects
- Demonstated knowledge of independently planning an experiment in aerodynamics
- Evaluation of experimental report
Strumenti a supporto della didattica
PPT slides and lecture notes will be periodically uploaded on Virtuale's platform.
A special section of the platform will be dedicated for sharing additional multi-media material (such as videos, research articles and link to specific websites) that will be uploaded by the teacher or by the students as suggested material.
In addition to the standard lectures, special lectures by invited speakers on advanced measurment techniques will possibly be organized.
