OVERVIEW

"The term aerodynamics is generally used for problems arising from flight and other topics involving the flow of air"

Ludwig Prandtl, 1949

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide students with the basic knowledge on the aerodynamics of bodies moving at subsonic speed in a fluid medium, and on both empirical/theoretical and computational methods to estimate forces and moments on wing profiles and finite-span wings.

AIMS AND LEARNING OUTCOMES

At the end of the course the student will have acquired a solid knowledge of the effects of fluid forces onto solid bodies in motion, for both airfoils (2D) and wings (3D), and will be capable of developing (i) simple models to extract salient features of the fluid/solid interaction, as well as (ii) more complex computational aerodynamics calculations. 

TEACHING METHODS

The course will consist mainly of lectures and applications of the concepts learned in class to the solution of practical aerodynamics problems. The second part of the course will consist mostly in practical experience in the computer room with open-source and commercial CFD codes.

EXAMS

EXAM DESCRIPTION

The exam will consist of a written test plus an oral examination. Students with SLD or any other regularly certified special educational needs are advised to contact the instructor at the beginning of the course to agree on teaching and examination methods that, in compliance with the course objectives, take into account individual learning requirements.

ASSESSMENT METHODS

At the end of the semester the students must take one written exams, for the instructor to monitor their level of comprehension of the topics covered. Furthermore, they will be asked to solve numerically some 2D aerodynamics problems by the use of the codes Xfoil, XFLR5 and ANSYS Fluent, and return a written report with a critical analysis of the results obtained.
