A vortex sheet based analytical model of the curled wake behind yawed wind turbines

Journal Article Bastankhah, Majid ; Shapiro, Carl R. ; Shamsoddin, Sina ; ... - Journal of Fluid Mechanics

Motivated by the need for compact descriptions of the evolution of non-classical wakes behind yawed wind turbines, we develop an analytical model to predict the shape of curled wakes. Interest in such modelling arises due to the potential of wake steering as a strategy for mitigating power reduction and unsteady loading of downstream turbines in wind farms. We first estimate the distribution of the shed vorticity at the wake edge due to both yaw offset and rotating blades. By considering the wake edge as an ideally thin vortex sheet, we describe its evolution in time moving with the flow. Vortexmore »« less

Numerical investigation of the influence of shear and thermal stratification on the wind turbine tip‐vortex stability

Journal Article Hodgkin, Amy ; Laizet, Sylvain ; Deskos, Georgios - Wind Energy

Summary The interaction between wind turbine wakes and atmospheric turbulence is characterised by complex dynamics. In this study, two major components of the atmospheric boundary layer dynamics have been isolated, namely, the mean velocity profile shear and the thermal stratification, to examine their impact on the near‐wake development by undertaking a series of highly resolved large‐eddy simulations. Subsequently, instantaneous flow fields are extracted from the simulations and used to conduct Fourier analysis and proper orthogonal decomposition (POD) and compute the mean kinetic energy fluxes by different POD modes to better understand the tip‐vortex instability mechanisms. Our findings indicate that shearmore »« less

Implications of Shear and Thermal Stratification on Wind Turbine Tip-Vortex Stability

Conference Hodgkin, Amy ; Laizet, Sylvain ; Deskos, Georgios

The interaction between wind turbines in a wind farm through their wakes is a phenomenon that has been studied for decades and is still relevant today. Turbines clustered together in arrays will often operate in the wake of other upstream turbines which may lead to significant power losses and fatigue loads. For modern large-scale wind turbines, the mean shear velocity profile and thermal stratification are major components of the atmospheric boundary layer so it is important to understand their impact on near-wake development. Additionally, veer is present due to the rotation of the Earth. The impact of shear, thermal stratificationmore »« less
Do ambient shear and thermal stratification impact wind turbine tip-vortex breakdown?

Journal Article Hodgkin, Amy ; Laizet, Sylvain ; Deskos, Georgios - Journal of Physics. Conference Series

Modern wind turbines experience uneven inflow conditions across the rotor, due to the ambient flow’s shear and thermal stratification. Such conditions alter the shape and length of turbine wakes and thus impact the loads and power generation of downstream turbines. To this end, understanding the spatial evolution of the individual wakes under different atmospheric conditions is key to controlling and optimising turbine arrays. With this numerical study we aim to obtain a better understanding of the fundamental physics governing the near-wake dynamics of wind turbines under shear and thermal stability, by examining their tip-vortex breakup mechanisms. Our approach considers scale-resolvingmore »« less

Accelerated Wind-Turbine Wake Recovery Through Actuation of the Tip-Vortex Instability

Journal Article Brown, Kenneth ; Houck, Daniel ; Maniaci, David ; ... - AIAA Journal

Advances in wind-plant control have often focused on more effectively balancing power between neighboring turbines. Wake steering is one such method that provides control-based improvements in a quasi-static way, but this does little to fundamentally change the wake recovery process, and thus, it has limited potential. This study investigates use of another control paradigm known as dynamic wake control (DWC) to excite the mutual inductance instability between adjacent tip-vortex structures, thereby accelerating the breakdown of the structures. The current work carries this approach beyond the hypothetical by applying the excitation via turbine control vectors that already exist on all modernmore »« less
