Gallery of URAPIV [in] motion

Here we intend to collect different snapshots of images and velocity vector fields, acquired by URAPIV users and analyzed by URAPIV, PyPIV and co. A kind of gallery of fluid motion by URAPIV

Bird flying in a tank seeded with small bubbles. It is dated back to 2000 and we unfortunately do not remember the name of the researcher. It was a biologist from UK, maybe Liverpool, maybe Bristol. In any case, we didn’t manage to analyze this image because it is of a special type of a single-frame and multiple-exposure images. When we started with URAPIV, the double-exposure was already replaced by the double-pulse principles and we didn’t program anything useful for this case. But it is still a beautiful shot.
