Experimental Characterisation of Swirl Stabilized Annular Stratified Flames [PDF]

, 2007
A burner for investigating lean stratified premixed flames propagating in intense isotropic turbulence has been developed. Lean pre-mixtures of methane at different equivalence ratios are divided between two concentric co-flows to obtain annular ...

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

Refinement of a Framework for Moving Aircraft River Velocimetry (MARV) and Application to Particle Tracking Along Alaskan Rivers

Water Resources Research
Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the ...

Three dimensional analysis of the exhalation flow in the proximity of the mouth

Heliyon
The human exhalation flow is characterized in this work from the three-dimensional velocimetry results obtained by using the stereo particle image velocimetry (SPIV) measurement technique on the flow emitted from a realistic airway model.

Tracing Flow Pathways of Nutrients in Dairy Farms—An End Member Mixing Analysis Approach

Hydrological Processes, Volume 40, Issue 6, June 2026.
Farm drain water at both farms was consistently a mixture of event water (rainwater and irrigation water) and soil water, which represent surface runoff and shallow subsurface soil flow, respectively. The dominance of end members varied between farms and events and was controlled by surface roughness, microtopography, and antecedent soil moisture ...

A Novel Polynomial Approach for Particle Image Velocimetry (PIV) Image Reconstruction

Fluids
Particle Image Velocimetry (PIV) often utilizes a cross-correlation method to determine how far particles have moved between two captured images. The most common methods for vector estimation use computationally exhaustive cross-correlation functions ...

Wheat flour particle size: Influence of mill design and effects on quality and performance

JSFA reports, Volume 6, Issue 6, Page 202-211, June 2026.
Abstract Among the various characteristics of wheat (Triticum aestivum) flour, particle size is of paramount importance globally. The industrial process of separating the three main components (endosperm, bran, and germ) must ensure that the desired quality is delivered to customers through a progressive reduction in the size of the endosperm until the

Sinogram‐based flow estimation in computed tomography using a physics‐informed neural network: Impact of gantry rotation speed, X‐ray fluence and pulsed acquisition on accuracy

Medical Physics, Volume 53, Issue 6, June 2026.
Abstract Background Non‐invasive imaging‐based assessment of blood flow plays a critical role in evaluating heart function and structure. Computed Tomography (CT) is a widely‐used imaging modality that can robustly evaluate cardiovascular anatomy and function, but direct methods to estimate blood flow velocity from movies of contrast dynamics have not ...
