Traceability of the Micro Scale Pipe Viscometer for Traceable Calibration of Dynamic Viscosity

Applied Sciences, 2023
Calibration of flow devices is important in several areas of pharmaceutical, flow chemistry and microfluidic applications where dosage of process liquids or accurate measurement of flow rate is important.

Cannula Pairing Determines Distal Limb Perfusion During Peripheral Veno‐Arterial Extracorporeal Membrane Oxygenation: An Experimental Mock‐Loop Study

Artificial Organs, EarlyView.
Introducer sheaths are commonly used as distal perfusion cannulas during VA‐ECMO; efficacy is uncertain. A simplified hydraulic bench experiment evaluated cannula and connection configurations during clinically relevant blood flow using water and simulated blood media. Distal flow fraction decreased with larger arterial cannulas and was not restored by

Indicators of Velocity Profile Distortion in Unsteady Laminar Pipe Flow

Fluids
Unsteady laminar pipe flows, prevalent in oscillating liquid columns, physiological pulsatile systems, and hydraulic transients, exhibit instantaneous velocity distributions that deviate significantly from the classical Hagen–Poiseuille parabolic profile.

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

New Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

Diversity and Plasticity of Hydraulic Traits Across a Relative Moisture Supply Gradient: Results From Multiple Common Gardens

Plant, Cell &Environment, Volume 49, Issue 12, Page 10207-10224, December 2026.
ABSTRACT Maintaining cellular hydration is essential for plant metabolic activity and carbon gain. Plants typically maintain hydration through efficiency of water transport networks, the ability to avoid network disruption, and retention of water via accumulation of osmotica. Given their global domain and their enduring presence across geological eras,

A Fractal Permeability Model of Tight Oil Reservoirs Considering the Effects of Multiple Factors

Fractal and Fractional, 2022
The prediction of permeability and the evaluation of tight oil reservoirs are very important to extract tight oil resources. Tight oil reservoirs contain enormous micro/nanopores, in which the fluid flow exhibits micro/nanoscale flow and has a slip ...

Adapting Pressurized Sample Infusion ESI‐MS for Real‐Time Monitoring of Heterogeneous Photoelectrocatalytic Reactions

Journal of Mass Spectrometry, Volume 61, Issue 11, November 2026.
ABSTRACT Pressurized sample infusion (PSI) enables real‐time electrospray ionization mass spectrometric (ESI‐MS) monitoring of reactions through continuous delivery of solution from a pressurized vessel. Existing PSI configurations, however, are not well suited to systems involving heterogeneous catalysts with strict geometric demands, such as TiO2 ...

Hagen-Poiseuille Flow in Semi-Elliptic Microchannels

, 2020
In this paper, an exact solution of Hagen-Poiseuille flow in microchannels with semi-elliptic cross sections is obtained. The velocity, shear stress distribution, and the friction factor are calculated and compared to known approximate solutions in the ...
