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.

Anisotropic double‐Gaussian analytical wake model for an isolated horizontal‐axis wind turbine
Energy Science & Engineering, 2022 An anisotropic double Gaussian (DG) model for analytical wake modeling to predict the streamwise wake velocity behind an isolated non‐yawed horizontal‐axis wind turbine is proposed.

Probabilistic estimation of the Dynamic Wake Meandering model parameters using SpinnerLidar-derived wake characteristics [PDF]
Wind Energy Science, 2021 We study the calibration of the Dynamic Wake Meandering (DWM) model using high-spatial- and high-temporal-resolution SpinnerLidar measurements of the wake field collected at the Scaled Wind Farm Technology (SWiFT) facility located in Lubbock, Texas, USA.

Journal of Physics: Conference Series, 2015 This paper presents a simple physical model to improve the currently used far-wake deficit models in the wind industry. The main improvement is deemed on the determination of the wake deficit in the near-wake. A Vortex Ring Model (VRM) is used to calculate the induced velocities in the near-wake, which are then coupled to the Jensen far-wake model and ...

Multiple Wind Turbine Wakes Modeling Considering the Faster Wake Recovery in Overlapped Wakes [PDF]
Energies, 2019 In a wind farm some wind turbines may be affected by multiple upwind wakes. The commonly used approach in engineering to simulate the interaction effect of different wakes is to combine the single analytical wake model and the interaction model. The higher turbulence level and shear stress profile generated by upwind turbines in the superposed area ...

The galactic wake model of the Magellanic Stream [PDF]
Symposium - International Astronomical Union, 1979 Tidal interaction models for the origin of the Magellanic Stream have been fairly successful in reproducing the radial velocities of the Stream (Lin and Lynden-Bell 1977, Davies and Wright 1977). However, no investigator has yet attained a self consistent treatment in which (1) the LMC and SMC are bound for at least 5×109 yr, (2) the passing Magellanic

A New Streamwise Scaling for Wind Turbine Wake Modeling in the Atmospheric Boundary Layer
Energies, 2022 In this study, we aim to investigate if there is a scaling of the streamwise distance from a wind turbine that leads to a collapse of the mean wake velocity deficit under different ambient turbulence levels.

The vortex wake of a ‘hovering’ model hawkmoth
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1997 Visualization experiments with Manduca sexta have revealed the presence of a leading–edge vortex and a highly three–dimensional flow pattern. To further investigate this important discovery, a scaled–up robotic insect was built (the ‘flapper’) which could mimic the complex movements of the wings of a hovering ...

Prediction of the Open-Water Performance of Ducted Propellers with a Panel Method
Journal of Marine Science and Engineering, 2018 In the present work, a comparison between the results obtained by a panel code with a Reynolds-averaged Navier-Stokes (RANS) code is made to obtain a better insight on the viscous effects of the ducted propeller and on the limitations of the inviscid ...

A mathematical model for a wake.
Michigan Mathematical Journal, 1984 A free boundary problem for a wake around an obstacle in a two dimensional incompressible, inviscid fluid flow has been considered. Sufficient conditions for the existence of wakes in doubly and simply connected starlike regions have been formulated.
