| Course contents : | Ever since the 18th century, researchers have known that one could simulate the movement of an object through still air by moving air against a static object. Nevertheless, the first wind tunnel was built by the Wright brothers in 1903. It was used to assist in the design of their No. 3 glider and, consequently the Wright Flyer. In fact, the development of aircraft design and wind tunnel tests have been going hand-in-hand ever since. Every major advance in aeronautical science and practice has been accompanied by ground breaking wind tunnel experiments. Additionally, wind tunnels started being applied to an increasingly wide range of engineering structures such as racing cars,
bridges and wind turbines.
Despite recent progress in Computational Fluid Dynamics, the wind tunnel is still an indispensable tool in the armoury of the aeronautical engineer. In fact, many CFD simulations are calibrated using wind tunnel results. Therefore, the importance of wind tunnel experiments remains paramount
to this day. |
|
| Course objective : | The aim of this course is to introduce students to the subject of low speed wind tunnel testing and to demonstrate practically all the major principles in the ULg wind tunnel. Some description of high-speed wind tunnels is also included in the course.
The detailed topics are:
- Introduction to the wind tunnel and its design
- Applications of wind tunnel testing
- Instrumentation
- Aerodynamic force balance
- Wind tunnel corrections
- High-speed wind tunnels |
|
| Prerequisites : | AERO0001-1 Aerodynamics
MECA0025-1 Fluid mechanics |
|
| Workshops : | -Wind tunnel laboratory sessions
-Worked examples in every structured learning session |
|
| Organization : | This is a first semester course. It is divided into 6 structured learning sessions and 6 wind tunnel sessions. A structured learning session is a combination of traditional lecturing with tutorial examples given to the students and solved with the assistance of the lecturer.
Each structured learning session will introduce a testing methodology that will then be practically applied during the corresponding wind tunnel session. The test cases will include current research activities of the ULg wind tunnel laboratory. |
|
| Written notes : | The lecture notes will be available online in the form of Powerpoint presentations.

| Assessment : | Assessment is performed through:
- A written exam
- An oral exam
- Assessment of the students' work during wind tunnel sessions |
