| Course contents : | The interaction of fluid flow with man-made structures is all around us and can result in both desirable and undesirable phenomena. For example, the sounds produced by wind instruments and the energy produced by wind turbines are positive fluid structure interactions. The destruction caused by a hurricane or the failure of a bridge due to flutter are undesirable fluid structure
interactions.
This courses introduces some of the most common fluid structure interaction phenomena, with emphasis on the undesirable ones. Design solutions for overcoming such phenomena will also be
discussed. The emphasis of the course will be on land constructions although some examples will concern marine architecture. |
|
| Course objective : | The aim of this course is to introduce students to the subject of fluid structure interaction.
The detailed topics to be introduced are:
- Bluff bodies and separated flow
- Vortex-induced vibration and lock-in
- Galloping vibrations and stall flutter
- Static divergence and flutter
- The atmospheric boundary layer
- Buffeting in wakes or turbulence
- Applications to design |
|
| Prerequisites : | AERO0001-1 Aerodynamics
MECA0025-1 Fluid mechanics
MECA0029-1 Theory of vibrations |
|
| Workshops : | Wind tunnel laboratory sessions on:
- Vortex shedding
- Bridge aerodynamics
Worked examples in every lecture |
|
| Organization : | This is a second semester course. It is divided into 8 structured learning sessions and two Matlab workshops.
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. |
|
| Written notes : | The lecture notes are available online in the form of Powerpoint presentations.
