## OVERVIEW

Basic course in aerodynamics

## AIMS AND CONTENT

LEARNING OUTCOMES

The course will provide the basis of the aerodynamics of bodies immersed in fluids moving at subsonic speeds, with particular reference to the concepts of boundary layer and velocity potential, with emphasis on the forces and moments acting on the body and provoking its movement.

TEACHING METHODS

The course will consist mainly of lectures and applications of the concepts learned in class to the solution of practical aerodynamics problems

SYLLABUS/CONTENT

• Introduction to Aerodynamics

-     Vorticity Dynamics

Vorticity and circulation; The vorticity equation; Generation of vorticity in incompressible flows

•  Ideal Fluids and Irrotational Flows

Plane potential flows, Conformal mapping and Joukowsky transformation, Potential flow around a cylinder; Lifting airfoils, Joukowsky airfoils; Potential flow around a two-dimensional body of arbitrary shape;Three-dimensional potential flows; Induced resistance and added mass force

•  Flow over Airfoils

Low speed flow over airfoils: the vortex sheet; The Kutta condition; Kelvin’s circulation theorem and the starting vortex; Symmetric airfoils; Cambered airfoils

•  Flow over Finite Wings

The vortex filament, Biot-Savart law and Helmholtz theorems; Prandtl’s classical lifting line theory

•  Boundary Layers

Falkner-Skan similarity solution; Hiemenz flow; Boundary layer over an infinite swept wing (FS-Cooke); Preliminary concepts on transition-to-turbulence of the boundary layer.

## EXAMS

EXAM DESCRIPTION

The exam will consist of a written test plus an oral examination.

ASSESSMENT METHODS

In the course of the semester, the students must take two partial exams, for the instructor to monitor their level of comprehension of the topics covered. Furthermore, to ascertain their maturity, critical thinking and capacity of synthesis, the writing of a term paper is required, on a topic chosen by the student and inherent to aerodynamics. The paper is then presented by each student to the whole class.
