Noise Measurement of a Wind Turbine using Thick Blades with Blunt Trailing Edge
The noise generated by wind turbines can potentially cause significant harm
to the ecological environment and the living conditions of residents.
Therefore, a proper assessment of wind turbine noise is crucial. The IEC
61400-11 standard provides standardized guidelines for measuring turbine noise,
facilitating the comparison of noise characteristics among different wind
turbine models. This work aims to conduct a comprehensive noise measurement of
a 100kW wind turbine using thick blades with blunt trailing edge, which differs
from the typical turbines studied previously. The work takes into account the
unique design and dynamic characteristics of small-scale wind turbines and
adjusts the measurement accordingly, with deviations from the IEC standards
will be explicitly addressed
Experimental Investigation of Airfoil Trailing Edge Noise Reduction by using TE Serrations
The growing prominence of aerodynamic noise from wind turbine blades at high
wind speeds has made it the primary source of noise for wind turbines, with
adverse effects on nearby residents' living conditions. This study focuses on
experimental research conducted in an anechoic wind tunnel to investigate the
noise reduction mechanism of wind turbine blade airfoils using serrated
trailing edges, aiming to contribute to the development of low-noise wind
turbine blades. Three models, including two types of NACA series airfoils and
one reference plate with attachable serrated trailing edges, were tested. The
findings reveal that airfoils with serrated trailing edges exhibit a 3 to 6 dB
reduction in the mid-high frequency wideband noise, with the width of the
frequency band of noise reduction slightly increasing as the Reynolds number
rises. The presence of serrations also eliminates multiple tones of high
amplitude exceeding 10 dB. The study highlights serration height as the most
influential factor for noise reduction, surpassing the significance of
serration width and the ratio of width to height. Moreover, investigations into
the noise reduction mechanism indicate varying degrees of reduction in
streamwise fluctuating velocity spectra near the serrated trailing edge, even
aligning with changes in the sound power spectra. Serrations were found to
alter the turbulence length scale in the downstream flow field, potentially
impacting noise generation. This study suggests that the reduction in
streamwise fluctuating velocity near the serrated trailing edge plays a crucial
role in noise reduction, highlighting the importance of detailed flow field
measurements and analysis for a comprehensive understanding of the mechanistic
relationship between flow changes and serration-induced noise reduction
14-Methoxy-2,16-dioxapentacyclo[7.7.5.01,21.03,8.010,15]henicosa-3(8),10,12,14-tetraene-7,20-dione
The title compound, C20H20O5, was synthesized from the reaction between 3-methoxysalicaldehyde and 1,3–cyclohexanedione in the presence of palladium(II) chloride. The two fused xanthene rings and one of the six-membered cyclohexane rings adopt envelope conformations, while the other six-membered cyclohexane ring is in a chair conformation. The molecular packing is stabilized by weak intermolecular C—H⋯O interactions
9-(4-Chlorophenyl)-4a-hydroxy-4,4a,5,6,9,9a-hexahydro-3H-xanthene-1,8(2H,7H)-dione
In the title compound, C19H19ClO4, the central fused ring and the attached cyclohexene ring adopt envelope conformations, while the cyclohexane ring adopts a chair conformation. The crystal packing is stabilized by O—H⋯O hydrogen bonds, which link the molecules into a chain along the b axis. Weak C—H⋯O bonds also occur
Reduced-order modeling of a sliding ring on an elastic rod with incremental potential formulation
Mechanical interactions between rigid rings and flexible cables are
widespread in both daily life (hanging clothes) and engineering system (closing
a tether net). A reduced-order method for the dynamic analysis of sliding rings
on a deformable one-dimensional (1D) rod-like object is proposed. In contrast
to discretize the joint rings into multiple nodes and edges for contact
detection and numerical simulation, a single point is used to reduce the order
of the numerical model. In order to achieve the non-deviation condition between
sliding ring and flexible rod, a novel barrier functional is derived based on
incremental potential theory, and the tangent frictional interplay is later
procured by a lagged dissipative formulation. The proposed barrier functional
and the associated frictional functional are continuous, hence the
nonlinear elastodynamic system can be solved variationally by an implicit
time-stepping scheme. The numerical framework is first applied to simple
examples where the analytical solutions are available for validation. Then,
multiple complex practical engineering examples are considered to showcase the
effectiveness of the proposed method. The simplified ring-to-rod interaction
model can provide lifelike visual effect for picture animations, and also can
support the optimal design for space debris removal system.Comment: 15 pages, 9 figure
A review of the spider genus Chthonopes (Araneae, Theridiosomatidae), with descriptions of two new species from China
The genus Chthonopes Wunderlich, 2011 is reviewed in this paper. The type species Chthonopes jaegeri Wunderlich, 2011 was illustrated based on new material from the type locality and the new distribution records (Bolikhamsay and Ban Kouanphavang Khammouane, Laos). Two new species are described from Yunnan, China: C. bifidum Yu & Lin, sp. nov. (♂♀) and C. jimudeng Yu & Lin, sp. nov. (♀). A key is provided for the genus, as well as species diagnoses, and a distribution map for all five species of Chthonopes
MX precipitate behavior in an irradiated advanced Fe-9Cr steel: Self-ion irradiation effects on phase stability
Reduced activation ferritic/martensitic (RAFM) steels are the leading
candidate structural materials for first-wall and blanket components in fusion
reactors. This work is the first in a series to provide a systematic roadmap of
MX precipitate stability in RAFM steels under various ion irradiation
conditions. Here, the MX-TiC precipitate behavior in an advanced Fe-9Cr RAFM
steel is assessed under self-ion irradiation to damage levels ranging from 1 to
100 displacements per atom (dpa) at temperatures ranging from 300-600{\deg}C to
isolate the effects of temperature and damage level on precipitate stability.
The pre-existing MX-TiC precipitates are shown to exhibit temperature-dominated
responses, including coarsening above 400{\deg}C at damage levels of 15 dpa,
while damage levels studied at 50 dpa and higher showed dissolution across all
temperature ranges studied. The effects of ballistic dissolution and diffusion
on precipitate behavior are outlined as a function of precipitate
characteristics (number density, size, and 25 volume fraction) and irradiation
parameters with the use of the recoil resolution model of precipitate
stability. This work provides critical insights into MX-TiC stability to high
dose in-order to further optimize advanced steels with improved radiation
resistance.Comment: 32 pages, 19 pages supplementa
