Data Validation for Particle Image Velocimetry,

Abstract

The application of Particle Image Velocimetry (PIV) to aerodynamic research in wind funnels results in a great number of PIV recordings which must be analyzed. Due to the great amount of data already contained in a single recording a fast and fully automatic processing of the PIV recordings is essential. After automatic evaluation of the PIV recordings a certain number of obviously incorrectly determined velocity vectors can usually be found by visual inspection of the raw data. In order to get rid of these incorrect data the raw flow field data have to be validated prior to further processing them. For this purposes special algorithms have to be developed which must also work automatically. (Author)
