Rotating-Disk-Based Hybridized Electromagnetic–Triboelectric Nanogenerator for Sustainably Powering Wireless Traffic Volume Sensors

open access: yes, 2016
Wireless traffic volume detectors play a critical role for measuring the traffic-flow in a real-time for current Intelligent Traffic System. However, as a battery-operated electronic device, regularly replacing battery remains a great challenge ...

Operational parameters and modes of rotary working body for harrowing crops [PDF]

open access: yesE3S Web of Conferences, 2019
A rotary working body with evenly spaced needles along perimeter is a flat disk (rotating in longitudinal–vertical plane). The technological process of interaction with soil is that when rolling rotary disk in soil layer, needle is introduced into it ...

Optimization of parameters and operating modes of the rotary working body for harrowing agricultural crops [PDF]

open access: yesE3S Web of Conferences, 2020
The rotary working body with evenly spaced needles along the perimeter is a flat disk (rotating in a longitudinally vertical plane). The technological process of interaction with the soil consists in the fact that when the rotary disk is rolled in the ...

Geometry of an Accelerated Rotating Disk [PDF]

open access: yesGeneral Relativity and Gravitation, 2004
We analyze the geometry of a rotating disk with a tangential acceleration in the framework of the Special Theory of Relativity, using the kinematic linear differential system that verifies the relative position vector of time-like curves in a Fermi reference.

Vibration characteristics of a functionally graded polymer nanocomposite shaft-disk rotor reinforced with graphene nanoplatelets

open access: yesPolymers and Polymer Composites, 2023
In this paper, a rotating functionally graded (FG) polymer nanocomposite shaft-disk assembly reinforced with graphene nanoplatelets (GPLs) resting on elastic supports is modelled and its vibration behaviours are analysed.

PIV measurement of vortical structures in a model of semiconductor single wafer cleaner

open access: yesNihon Kikai Gakkai ronbunshu, 2014
In a single wafer spin cleaner, the wafer is rotated at high speed to spin off ultrapure water and clean air is blown perpendicular onto the surface to dry the wafer.

Effects of wall compliance on the laminar–turbulent transition of torsional Couette flow [PDF]

open access: yes, 2003
Torsional Couette flow between a rotating disk and a stationary wall is studied experimentally. The surface of the disk is either rigid or covered with a compliant coating.

Experimental Measurements of the Natural Frequencies and Mode Shapes of Rotating Disk-Blades-Disk Assemblies from the Stationary Frame

open access: yesApplied Sciences, 2019
Determining the natural frequencies and mode shapes of rotating turbomachinery components from both rotating and stationary reference frames is of paramount importance to avoid resonance problems that could affect the normal operation of the machine, or ...
