Application of Particle Image Velocimetry - Theory and Practice

Kurzfassung

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