    1. Author: J Carlier, CEMAGREF, Rennes
      Images with synthetic particles and scalar based on DNS of self sustained 2D turbulence (download here).


    2. Author: J. Carlier CEMAGREF, Rennes
      Synthetic image sequences of analytic flows, (download here).

    3. Package 3
      Author: B.Wieneke
      Sequence of experimental time-resolved PIV images showing a slightly turbulent air flow with small water droplets with a diameter of about 5 micrometer. The sequence has been recorded with a Photron APX camera with 1024 x 1024 pixel running at 1000 Hz. The field of view is about 7 x 7 cm.

    4. Package 4
      Authors: B.Wieneke, LaVision and F.Scarano, TU-Delft
      Synthetic PIV image with different flow gradients and noise This image is used in the current PIV-Challenge 2005 (case A4) It has been designed in a way to analyse the capability of 2D-PIV algorithms to cope with different degrees of local flow gradients without and with varying degrees of image noise. The purpose was to design a single image which shows immediately in a visual as well as quantitative way the strengths and weaknesses of a particular algorithm.

    5. Package 6
      Author: B.Wieneke,
      This data set contains synthetically generated volumes with seeding particles. Volume size: 512 x 513 x 33 voxel (nx,ny,nz). The source 2D-images and calibration data are also provided. It is a good starting point to test ones tomographic reconstruction, 3D-cross-correlation or particle tracking algorithms.

    6. Package 9
      Authors: F.Scarano, TU-Delft and D.Michaelis, LaVision et.al.
      Experimental volume PIV-data. This data package contains of two volumes computed by tomographic reconstruction (Tomographic-PIV).It is a Karman street behind a cylinder, which is positioned to the right of the volume, with the water flow going to the left.

    7. Package 10
      Author: B.Wieneke,
      Experimental LIF images. The supplied sequence of 20 images has been recorded in water where another fluid with a certain fraction of carbonoxy snarf which is pH-sensitive. The images have been illuminated with a laser light sheet at 532 nm detected by two cameras having filters for two different wavelength ranges (image set SNARF-1 and SNARF-2). The ratio of the two intensities is proportional to the pH-value (set SNARF-pH).
