CODE 65906 ACADEMIC YEAR 2017/2018 CREDITS 6 cfu anno 2 INGEGNERIA MECCANICA - ENERGIA E AERONAUTICA 9270 (LM-33) - SCIENTIFIC DISCIPLINARY SECTOR ING-IND/06 LANGUAGE Italian TEACHING LOCATION SEMESTER 1° Semester TEACHING MATERIALS AULAWEB 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.

Exam Board ALESSANDRO BOTTARO (President) ANDREA MAZZINO JAN OSCAR PRALITS LESSONS Class schedule AERODYNAMICS 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.
