General Defocusing Particle Tracking: fundamentals and uncertainty assessment

open access: yes, 2020
General Defocusing Particle Tracking (GDPT) is a single-camera, three-dimensional particle tracking method that determines the particle depth positions from the defocusing patterns of the corresponding particle images.

Nonequilibrium Period with Emergence of Marangoni Circulations in Meniscus Splitting

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 5, 4 March 2026.
The emergence and evolution of Marangoni convection in the meniscus splitting phenomenon are investigated. During the mass circulation of viscous fluids, the confluence and bifurcation of polymer dispersions beneath the evaporative interface lead to the inhomogeneous densification of the skin layer.

PIV Analysis of Ludwig Prandtl's Historic Flow Visualization Films [PDF]

open access: yes, 2010
Around 1930 Ludwig Prandtl and his colleagues O. Tietjens and W. M\"uller published two films with visualizations of flows around surface piercing obstacles to illustrate the unsteady process of flow separation.

Aerospace Engineering Undergraduate Laboratory Courses: A Systematic Review (1990–2025)

open access: yesComputer Applications in Engineering Education, Volume 34, Issue 2, March 2026.
ABSTRACT This review examines the evolution of undergraduate aerospace engineering (AE) laboratories from 1990 to 2025, focusing on course formats, pedagogy, technology, and assessment. Once centered on traditional demonstration‐based exercises, AE laboratories have increasingly shifted toward hands‐on, project‐based, and hybrid physical‐virtual models

Experimental and computational investigation on the macroscopic circulation patterns in a bubbling gas-solid fluidized bed [PDF]

open access: yes, 2009
The hydrodynamics of a freely bubbling, pseudo 2-D fluidized bed has been investigated experimentally for different bed aspect ratios at different superficial gas velocities by using Particle Image Velocimetry (PIV) combined with Digital Image Analysis ...

Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]

open access: yes, 2019
An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological ...

Application of Particle Image Velocimetry (PIV) Method in Pipe-Soil Interaction Problems

open access: yesGeo-Congress 2023, 2023
In this study, the effect of the embedment ratio of the pipe was investigated using the PIV method. The difference in this study compared to the literature is that in the case of the surcharge load, the failure surfaces were determined experimentally depending on the burial depth of the pipe.

A Comprehensive Library of Stenosis Geometrical Models: Review and Guidelines for Hemodynamic Simulations and Stent Design

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
Classification of blood flow regimes: Spatial variation of endothelial shear stress (ESS) patterns across an atherosclerotic lesion. ABSTRACT Accurate geometrical representation of stenosis is essential for stent design, surgical planning, and computational fluid dynamics (CFD) simulations, as even minor shape variations significantly alter hemodynamic

Two‐Photon Microbubble Printing: Asymmetric Assembly for Continuous Laser Writing

open access: yesSmall, Volume 22, Issue 18, 25 March 2026.
Two‐photon microbubble printing is reported that combines nonlinear photochemistry with thermally driven fluid dynamics. At the laser focus, a distorted vapor bubble induce a strong rear‐to‐front convective flow. By enabling asymmetric assembly, this method allows the continuous formation of nanoparticle aggregates from a wide variety of materials ...
