Validation of the granular temperature prediction of the kinetic theory of granular flow by particle image velocimetry and discrete particle model [PDF]

open access: yes, 2004
In order to give a detailed description of the hydrodynamics in large industrial scale fluidized beds, continuum models are required. Continuum models often use the kinetic theory of granular flow (KTGF) to provide closure equations for the internal ...

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

open access: yesHeat 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

Wind Tunnel Assessment of Dynamic Induction Control Under Varying Inflow Wind Directions

open access: yesWind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT Dynamic induction control (DIC), also known as pulse control, is a wake‐mixing strategy intended to improve wind farm efficiency by mitigating wake‐induced power losses. It typically employs harmonic collective blade pitching to excite wake instabilities, forming coherent pulsing structures that enhance turbulent mixing and accelerate wake ...

Multiscale Coupling of Boundary Layer Flow Turbulence and Sand Streamer Dynamics

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Wind‐driven sand transport at the Earth's surface exhibits pronounced spatiotemporal variability, forming elongated sand streamers that critically control sand flux. Despite their importance, the detailed fundamental mechanisms governing streamer formation remain elusive.

Imaging Velocimetry Measurements for Entropy Production in a Rotational Magnetic Stirring Tank and Parallel Channel Flow

open access: yesEntropy, 2009
An experimental design is presented for an optical method of measuring spatial variations of flow irreversibilities in laminar viscous fluid motion. Pulsed laser measurements of fluid velocity with PIV (Particle Image Velocimetry) are post-processed to ...

Unique Phenomena in Different Viscosity Mixing and Suitable Operating Methods

open access: yesChemical Engineering &Technology, Volume 49, Issue 5, May 2026.
Flow visualization was used to clarify the mixing behavior of high‐ and low‐viscosity fluids in stirred vessels. Large impellers enabled relatively easy mixing, whereas certain impellers generated unusual flow patterns under zero‐gap interfacial conditions.

Silicone-Based Molding Technique for Optical Flow Analysis in Transparent Models of Fluidic Components

open access: yesApplied Sciences, 2018
Optical flow analysis methods such as particle image velocimetry can only be performed in fluid systems or components with optical access. Many fluidic components, such as metallic tubes, do not typically feature optical accessibility.

Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 1884-1904, May 2026.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.
