Clarification of influences of inflow conditions on wake of horizontal axis wind turbine

Nihon Kikai Gakkai ronbunshu, 2015
In recent years, wind turbines are introduced in wind farms in which some wind turbines are concentrated. When wind turbines are built in contiguity with each other in wind farms, the flow passing through a wind turbine, which is called wake, may flow ...

A Modeling Method of Ship Acoustic Wake Echo Signal

水下无人系统学报, 2023
It is an important way to study the ship wake by building simulation data through the acoustic wake echo signal model. At present, the scattering echo of a single bubble is ignored in the existing models. Therefore, a point scattering model for different

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Study of Generalized Interaction Wake Models Systems with ELM Variation for Off-Shore Wind Farms

Energies, 2019
This paper reports a novel frandsen generalized wake model and its variation model-frandsen generalized normal distribution wake model for off-shore wind farms. Two different new wake models in off-shore wind farms have been studied comparatively.

A time‐varying formulation of the curled wake model within the FAST.Farm framework

Wind Energy, 2023
In this article, we present a time‐varying formulation of the curled wake model that we implemented in FAST.Farm. The curled wake model, originally developed for steady‐state conditions, is used to produce realistic wake profiles behind a wind turbine in

Upward Shift of Wind Turbine Wakes in Large Wind Farms

Energies, 2023
A detailed description of wake characteristics is essential for optimizing wind farm performance. Compared with the wake of a stand-alone wind turbine, less attention has been paid to wind turbine wakes in large wind farms.

Electroencephalographic Normalization as a Biomarker of Clinical Recovery in Down Syndrome Regression Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Down syndrome regression disorder is a syndrome characterized by subacute loss of cognitive, behavioral, and functional abilities in individuals with Down syndrome. Electroencephalography abnormalities are frequently observed during evaluation, but it remains unclear whether these findings represent a dynamic marker of disease ...

Investigation of Wake Expansion for Spanwise Arranged Turbines in the Offshore Wind Farm by Large Eddy Simulation

Energies
The issue of wind turbine wake effects in the offshore environment has become increasingly important with the development of offshore wind farms. The problem of wake dispersion from turbines plays a crucial role in evaluating the wake velocity deficit ...

A Simplified Numerical Model for the Prediction of Wake Interaction in Multiple Wind Turbines

Energies, 2019
In the design of wind energy farms, the loss of power should be seriously considered for the second wind turbine located inside the wake region of the first one.
