Real-Time Measurement of Flash-Flood in a Wadi Area by LSPIV and STIV
Hydrology, 2019 Flash floods in wadi systems discharge large volumes of water to either the sea or the desert areas after high-intensity rainfall events. Recently, wadi flash floods have frequently occurred in arid regions and caused damage to roads, houses, and ...

3D Particle Tracking Velocimetry Method: Advances and Error Analysis [PDF]
, 2005 A full three-dimensional particle tracking system was developed and tested. By using three separate CCDs placed at the vertices of an equilateral triangle, the threedimensional location of particles can be determined.

Graph-enhanced neural operator for missing velocities reconstruction in river surface velocimetry
Machine Learning. EarthMeasuring river surface velocity is essential for estimating river discharge. While traditional image-based velocimetry methods are often effective, they struggle to produce complete velocity fields under complex environmental conditions. Factors such as

X-Ray imaging method for in-situ study of particle-laden flows
e-Journal of Nondestructive TestingThe accurate measurement of flow parameters often depends on sensor accessibility. Optical flow assessment techniques, such as Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV), are limited to optically transparent media. However,

Rotor-Obstacle Aerodynamic Interaction in Hovering Flight: An Experimental Survey [PDF]
, 2016 Despite the presence of a fair number of numerical and experimental works on the rotor-obstacle interaction, a systematic study of the aerodynamic phenomena involved is lacking.

International Journal of Advanced Robotic Systems, 2019 The development of microelectromechanical systems based on magnetohydrodynamic for micro-robot applications requires precise control of the micro-flow behavior. The micro-flow channel design and its performance under the influence of the Lorentz force is
