Low Reynolds Number Flow in a Packed Bed of Rotated Bars
Chemical Engineering &Technology, Volume 49, Issue 6, June 2026.Research Article: This study examines gas flow in a modular packed‐bed reactor with square bars arranged in rotated layers, creating complex void spaces. Using particle image velocimetry, measurements were taken at Reynolds numbers of 100 and 200. These results validated two particle‐resolved numerical simulations employing boundary‐conforming meshing ...

Hydrodynamics in a Bubble Column—Part 2: Three‐Phase Flow
Chemical Engineering &Technology, Volume 49, Issue 6, June 2026.Multiphase computational fluid dynamics (CFD) simulation is a useful tool to study the hydrodynamics in a bubble column, if appropriate closure models exist. The present study extends a previous database to three‐phase flow experiments. This is achieved by using a combination of particle image velocimetry (PIV) and shadowgraphy to measure all phases ...

Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

Hydrodynamic and ecological effects of engineered logjams: Insights from field observations
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Drone imaging, LSPIV and electrofishing data quantified restoration effects of engineered logjam at the Emme River (Switzerland). Placement and discharge shaped flow: Side jams created longer wakes, centre jams stronger mixing; and lower discharge intensified gap velocities, whereas wake length remained stable.

DEVELOPMENT OF THE PARTICLE IMAGE VELOCIMETRY (PIV) TECHNIQUE FOR THREE DIMENSIONS: TUNNELING VELOCIMETRY [PDF]
, 2002 "Conventional velocimetry has an intrinsic limitation because it yields 2D data, neglecting the third velocity component. For this reason, 3D-PIV has recently evolved as an area of research with success at the cost of increasing complexity in its ...

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
Heat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

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,
