Abstract
  • A novel approach for the time-resolved analysis of high -speed sequences of particle images is presented. The proposed method aims at the minimization of PIV errors in the lower velocity range by adjusting locally and dynamically the interframe time interval of the PIV pairs in a recorded high-speed sequence. The algorithm performs the operation on a local basis, thus providing the same level of accuracy across the full velocity dynamic range of the flow. The present results indicate a greater performance than state-of-the-art PIV analysis based on multi-grid offset PIV and is successfully applied to synthetic and real flow cases. (literal)
