Monocular 3D Micro-PIV System Using Computational Imaging

IEEE Photonics Journal
A three-dimensional (3D) particle image velocimetry (PIV) system typically consists of multiple cameras. However, micro-PIV systems for measuring microscale velocity fields lack sufficient space to accommodate them. In this work we propose an alternative

Comparative analysis of counter-current and co-current downer reactors using particle image velocimetry and computational particle-fluid dynamics

Chemical Engineering Journal Advances
We investigated the hydrodynamics in co- and counter-current downer operations using particle image velocimetry (PIV) and computational particle fluid dynamics simulations (CPFD).

Setup of Particle Image Velocimetry (PIV) in Hypersonic Flows

, 2008
The accuracy of numerical methods in calculating the flow of backward facing steps in turbulent hypersonic flows is limited due to a lack of flow measurements. Such measurements are necessary to validate numerical techniques and turbulent models.
