A Swirling-Flow-Enhanced Triboelectric Nanogenerator for Improved Dilute-Phase Particle Sensing [PDF]

open access: yesSensors
Precise measurement of particle concentration in dilute gas–solid two-phase flows is challenging due to low particle loading and stochastic particle motion, which lead to weak signals and detection blind zones.

Color-coded circulation for visualizing swirling flow with a 3-dimensional helical stent in the superficial femoral artery [PDF]

open access: yesRadiology Case Reports
Color-coded circulation is a display method that generates dynamic color-coded images based on the time of arrival of contrast agents using parametric imaging to create video displays.

Stochastic Chaos in a Turbulent Swirling Flow [PDF]

open access: yesPhysical Review Letters, 2017
We report the experimental evidence of the existence of a random attractor in a fully developed turbulent swirling flow. By defining a global observable which tracks the asymmetry in the flux of angular momentum imparted to the flow, we can first reconstruct the associated turbulent attractor and then follow its route towards chaos.

The Viscoelastic Swirled Flow in the Confusor [PDF]

open access: yesPolymers, 2021
A two-dimensional mathematical model for a steady viscoelastic laminar flow in a confusor was developed under the condition of swirled flow imposed at the inlet. Low density polyethylene was considered as a working fluid. Its behavior was described by a two-mode Giesekus model.

Fluid-dynamic optimal design of helical vascular graft for stenotic disturbed flow. [PDF]

open access: yesPLoS ONE, 2014
Although a helical configuration of a prosthetic vascular graft appears to be clinically beneficial in suppressing thrombosis and intimal hyperplasia, an optimization of a helical design has yet to be achieved because of the lack of a detailed ...

Effect of swirl on fluctuation of pressure drop in a gas–liquid slug flow

open access: yesMeasurement: Sensors, 2020
Slug flow as one of the typical two-phase flow patterns occurs widely in industry. The fluctuating phenomenon in slug flow is harmful to the pipeline system and should be suppressed.

Measurement and prediction on the liquid film thickness of swirling annular flow

open access: yesMeasurement: Sensors, 2020
In this study, the liquid film thickness of swirling annular flow has been measured by parallel conductivity probes. The differences of the liquid film between vertically downward swirling annular flow and straight flow have been investigated.
