A significant feature of PIV and LPT is that a reliable basis of experimental flow field data is provided for direct comparison with numerical calculations and hence, for validation of flow simulation codes. During the last years an increasing number of scientists have started to utilize the PIV and LPT techniques to investigate the instantaneous structure of velocity fields in various areas of fluid mechanics. A large number of different approaches for the recording and evaluation of tracer particle images have been described in literature. This course, which is the 29th Course on PIV since 1993 organized by DLR, will mainly concentrate on those aspects of the theory of PIV and LPT relevant to applications. Besides giving lectures on the fundamental aspects, special emphasis is placed on the presentation of practical and reliable solutions of problems which are faced during the implementation of these techniques in wind tunnels and other test facilities. During practice the participants will have the opportunity to carry out the recording and the evaluation of PIV and LPT images by themselves in small groups. Matured developments of the PIV technique such as Stereo PIV, Time Resolved PIV, Micro-PIV and recent innovations in 3D(t)-PIV/3D-PTV (tomographic and digital holographic PIV, LPT Shake-The-Box) will be discussed and demonstrated.

The PIV Course 2022 will take place as an interactive online seminar and practice!
