Application of Particle Image Velocimetry - Theory and Practice -

Abstract

For investigations of flow fields with pronounced spatial structures and/or rapid temporal or spatical changes new experimental techniques, such as Particle Image Velocimetry (PIV) are required which allow to capture large flow velocity fields instantaneously. A number of different approaches for the recording and evaluation of PIV images has been described in literature. This course will mainly concetrate on those aspects of the theory of PIV relevant to applications. Besides giving lectures on the fundamental aspects, special emphasis is placed on the presentation of practial and reliable solutions of problems whichare faced during the implementation of this technique in wind tunnelsand other test facilities. During practice the participants will havethe opportunity to carry out the recording and the evaluation of PIV photographs for themselves in small groups.
