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

Underwater LED-based Lagrangian particle tracking velocimetry

Journal of Visualization, 2022
Abstract A new white-light volumetric flow measurement technique is presented that can be used in large-scale facilities. The technique enables large volumes to be measured with high temporal and spatial resolution and without the need for a class-4 laser.

Study on visualization of water mixing flows in a digester equipped with a vertical impeller by using radiotracers

Nuclear Engineering and Technology, 2020
A mixer with a new concept design has been adapted into water treatment plants. It reportedly cuts down the energy consumption of the mixer by the new mixer, which moves vertically and creates internal flows toward its bottom.

Considerations When Applying Large-Scale PIV and PTV for Determining River Flow Velocity

Frontiers in Water, 2021
Large-scale image velocimetry is a novel approach for non-contact remote sensing of flow in rivers. Research within this topic has largely focussed on developing specific aspects of the image velocimetry work-flow, or alternatively, testing specific ...

Particle retracking algorithm capable of quantifying large, local matrix deformation for traction force microscopy

PLoS ONE, 2022
Deformation measurement is a key process in traction force microscopy (TFM). Conventionally, particle image velocimetry (PIV) or correlation-based particle tracking velocimetry (cPTV) have been used for such a purpose.

Simultaneous 3D tracking and temperature measurements of L-PBF spatter particles using a single camera

Additive Manufacturing Letters, 2023
This work discusses the implementation of a novel technique for simultaneous 3D particle tracking velocimetry and dual-wavelength pyrometry of spatter particles ejected during the Laser-Powder Bed Fusion (L-PBF) process using a single high-speed spectral

Comparison of particle image velocimetry and the underlying agents dynamics in collectively moving self propelled particles

Scientific Reports, 2023
Collective migration of cells is a fundamental behavior in biology. For the quantitative understanding of collective cell migration, live-cell imaging techniques have been used using e.g., phase contrast or fluorescence images.

A hybrid particle tracking algorithm for characterizing particle motions in pneumatic dispersion [PDF]

AIP Advances
Accurate measurement of particle motion in pneumatic dispersion is essential, yet challenging, because current imaging techniques cannot clearly resolve individual particles within dense agglomerations.
