Particle image velocimetry

, 1993
This document describes the development of a new flow visualization and measurement facility that incorporates a sheet of laser light and digital image enhancement and processing techniques. A simple bench test that was used to demonstrate the feasibility of such techniques is also described.

Meniscus‐guided organic semiconductor single crystals: From fluid dynamics to morphology control and multifunctional applications

FlexMat, EarlyView.
Centered on the multiscale meniscus, this review dissects mass transport in meniscus‐guided coating into parallel and lateral components. By analyzing the balance of multiple factors during crystallization, it establishes a clear morphology‐performance relationship.

Investigation on spatial breakup characteristics of low-pressure jets with particle image velocimetry experiment and volume of fluid–level set simulation

Advances in Mechanical Engineering, 2016
In order to study the spatial breakup characteristics of the initial section of low-pressure jets, an experiment was performed to investigate the flow fields and concentration fields of jet flows with different nozzle geometric parameters and also the ...

AWSD Reactive Burn Model for the HMX‐Based High Explosive LX‐04

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT An Arrhenius–Wescott–Stewart–Davis (AWSD) reactive burn model is applied to describe shock initiation and detonation properties of the HMX‐based high explosive LX‐04. The parameters in the model are calibrated to data from multiple sources. The thermodynamic equations of state used in the model are calibrated to a combination of thermochemical

Information Entropy Analysis of a PIV Image Based on Wavelet Decomposition and Reconstruction

Entropy
In particle image velocimetry (PIV) experiments, background noise inevitably exists in the particle images when a particle image is being captured or transmitted, which blurs the particle image, reduces the information entropy of the image, and finally ...

Validation of a Particle Image Velocimetry Algorithm Through Comparative Field and Laboratory Analysis

River Research and Applications, EarlyView.
ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

Magnetohydrodynamic velocity profile measurement for microelectromechanical systems micro-robot design

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

Mechanical stiffness orchestrates distinct regulation of MRTFs and YAP/TAZ transcriptional cofactors in hepatocytes

The FEBS Journal, EarlyView.
MRTFs and YAP/TAZ proteins, or mechanosensitive transcriptional cofactors (MRTcoF), regulate common genes associated with cellular contractility and immune cell infiltration. Their differential regulation in response to stiffness is linked to changes in hepatocyte's aspect ratio. MRTFB does not undergo nuclear translocation under these conditions. This

Assessing the reproducibility of a bioimage analysis workflow characterising tissue flow in Drosophila

Journal of Microscopy, EarlyView.
Abstract Reproducibility challenges in bioimage analysis are common. The proliferation of tools and workflows creates a complex ecosystem that is difficult to reproduce without deliberate, explicit reporting and support. We assess the reproducibility of Gehrels et al.(2023) as a representative bioimage analysis workflow.

Droplet size spectrum, velocity, angle and flow rate of pulse‐width‐modulated spray nozzles with adjuvants

Pest Management Science, Volume 82, Issue 9, Page 8831-8843, September 2026.
Optimizing PWM performance requires not only appropriate duty cycle selection, but also careful choice of adjuvant formulation tailored to each nozzle type. Drift control agents increased droplet size and reduced fine droplets, mitigating PWM‐induced variability. Decreasing the duty cycle consistently narrowed the spray angle.
