17352 - Laboratory of Experimental Aerodynamics

Learning outcomes

At the end of the course the student should understand the basic aspects of the experimental aerodynamics and should be able to perform by himself experimental studies by means of the standard experimental equipment normally available in applied aerodynamic laboratories.

Lecture notes

Teaching methods

The course is given in English. Lectures and frontal exercises are held by the teacher. At the end of the lectures the students, in groups of 4-5 units, will carry out an experiment in the aerodynamics laboratory. At the same time the student will perform a small CFD analysis (with open source softwares) on a cylinder shedding.

The acquired data will have to be processed and will be the subject of a final technical report.

Assessment methods

The assessment methods is based on a periodic check of the activity carried out by the student and on a final discussion on the written report. At the end of the discussion, in case of positive response the exam is considered "passed" and the CFU assigned.

Teaching tools

PowerPoint presentations and CICLoPE laboratory equipment are used. Small CFD simulations will be carried out on the students' personal computers using open source software.
