The Influence of Different Wake Profiles on Losses in a Low Pressure Turbine Cascade †
International Journal of Turbomachinery, Propulsion and Power, 2018 Large eddy simulations were carried out in order to investigate the influence of unsteady incoming wakes with different profiles on the loss mechanisms of the high lift T106Alinear low-pressure turbine (LPT) cascade. Bars placed upstream of the LPT blade

Do wind turbines pose roll hazards to light aircraft? [PDF]
Wind Energy Science, 2018 Wind energy accounted for 5.6 % of all electricity generation in the United States in 2016. Much of this development has occurred in rural locations, where open spaces favorable for harnessing wind also serve general aviation airports. As such,

Leading effect for wind turbine wake models
Renewable Energy, 2023 As wind energy expands worldwide, the demand of reliable, fast, cost-efficient wind turbine wake models is growing. This is a significant challenge as wind turbines face various inflow conditions, that include turbulence, inhomogeneities/instationarities and upstream wakes.

Bidirectional wakes over complex terrain using SCADA data and wake models [PDF]
Wind Energy ScienceWe investigate bidirectional wake effects between two wind turbines of the same type in a hill region in northern Japan using supervisory control and data acquisition (SCADA) data and validate the simulated wakes using 12 wake models. The extent to which

Power and Flow Analysis of Axial Induction Control in an Array of Model-Scale Wind Turbines
Energies, 2022 As research on wind energy has progressed, it has broadened from a focus on the wind turbine to include the entire wind farm. In particular, methods to mitigate the negative effects of upstream wakes on downstream turbines have received significant ...

Field Measurements of Wind Turbine Wakes with Lidars [PDF]
Journal of Atmospheric and Oceanic Technology, 2013 AbstractField measurements of the wake flow produced from a 2-MW Enercon E-70 wind turbine were performed using three scanning Doppler wind lidars. A GPS-based technique was used to determine the position of the wind turbine and the wind lidar locations, as well as the direction of the laser beams.

MULTIFRACTAL ANALYSIS OF A WAKE FOR A SINGLE WIND TURBINE [PDF]
Topical Problems of Fluid Mechanics 2017, 2017 Wind energy is an important component of renewable energy sources. Studying of turbulent wakes for wind turbines and interactions with Atmospheric Boundary Layer is an urgent problem. The theory of chaos and fractal geometry with some research in fluid dynamics will change profoundly the scope of complex scale to scale transport in theory of turbulence,
