Unsupervised Learning of Particle Image Velocimetry [PDF]
, 2020 Particle Image Velocimetry (PIV) is a classical flow estimation problem which is widely considered and utilised, especially as a diagnostic tool in experimental fluid dynamics and the remote sensing of environmental flows. Recently, the development of deep learning based methods has inspired new approaches to tackle the PIV problem.

Dual wavelength digital holography for 3D particle image velocimetry [PDF]
Journal of the European Optical Society-Rapid Publications, 2015 A multi-exposure digital in-line hologram of a moving particle field is recorded by two different wavelengths and at different times. As a result, during the reconstruction step, each hologram can be independently and accurately reconstructed for each ...

Digital particle image velocimetry measurements of the downwash distribution of a desert locust Schistocerca gregaria [PDF]
, 2006 Actuator disc models of insect flight are concerned solely with the rate of momentum transfer to the air that passes through the disc. These simple models assume that an even pressure is applied across the disc, resulting in a uniform downwash ...
