Adaptive particle image velocimetry based on sharpness metrics
Journal of the European Optical Society-Rapid Publications, 2018 Background Optical distortions can significantly deteriorate the measurement accuracy in particle image velocimetry systems. Such distortions can occur at fluctuating phase boundaries during flow measurement and result from the accompanied refractive ...

Particle image velocimetry with optical flow [PDF]
Experiments in Fluids, 1998 An optical Flow technique based on the use of Dynamic Programming has been applied to Particle Image Velocimetry thus yielding a significant increase in the accuracy and spatial resolution of the velocity field. Results are presented for calibrated synthetic sequences of images and for sequences of real images taken for a thermally driven flow of water

Experimental study on seepage erosion based on transparent soil and particle tracing technology
Yantu gongcheng xuebao, 2022 Seepage erosion is one of the main reasons for the instability and failure of hydraulic engineering. In the process of seepage erosion, the fine particles of the soil are gradually lost, and the permeability of the soil is enhanced, which further affects
