Images with synthetic particles and scalar based on DNS of self sustained 2D turbulence

Synthetic image sequences of analytic flows,
- Package 3
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.

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.
- Package 6
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.
- 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.
- Package 10
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).
