Two-way coupling of gravity waves and wind farm wakes: a reduced-order boundary-layer model
Hossein A. Kafiabad, Majid Bastankhah
This paper develops a reduced-order numerical framework for modelling the two-way coupling between gravity waves and turbulent wakes in large-scale wind farms. Starting with the no…
Optimal wind farm energy and reserve scheduling incorporating wake interactions
Marin Mabboux-Fort, Majid Bastankhah, Peter C Matthews +1
This paper proposes a novel approach for optimal energy and reserve scheduling of wind farms by explicitly modelling wake interactions to enhance market participation and operation…
Assessing engineering wake models against operational data: insights from the Lillgrund wind farm wake steering campaign
Diego Siguenza-Alvarado, Matthew Harrison, Mohammadreza Mohammadi +4
Validating engineering wake models under real-world operational conditions is essential for improving wind farm performance predictions. This study uses a unique dataset from the L…
Generalised actuator disk theory: wake development with turbulent entrainment
Majid Bastankhah, Peter E. Hydon, Carl Shapiro +2
Classical actuator disk theory, developed more than a century ago, provides an idealised description of turbine rotor performance. It treats a rotor as an infinitesimally-thin perm…
Analytical modelling of wind-turbine wake turbulence in neutral atmospheric boundary layers
Frédéric Blondel, Erwan Jézéquel, Helen Schottenhamml +1
So-called engineering or analytical wind farm flow solvers typically build upon two submodels: one for the velocity deficit and one for the wake-added turbulence intensity. While v…
Modelling turbulence in axisymmetric wakes: an application to wind turbine wakes
Majid Bastankhah, Jenna K. Zunder, Peter Hydon +2
A novel fast-running model is developed to predict the three-dimensional (3D) distribution of turbulent kinetic energy (TKE) in axisymmetric wake flows. This is achieved by mathema…
A fast-running physics-based wake model for a semi-infinite wind farm
Majid Bastankhah, Mohammad Mehdi Mohammadi, Charlie Lees +3
This paper presents a new generation of fast-running physics-based models to predict the wake of a semi-infinite wind farm, extending infinitely in the lateral direction but with f…
A vortex sheet based analytical model of the curled wake behind yawed wind turbines
Majid Bastankhah, Carl R. Shapiro, Sina Shamsoddin +2
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 wak…
Analytical solution for the cumulative wake of wind turbines in wind farms
Majid Bastankhah, Bridget L. Welch, Luis A. Martínez-Tossas +2
This paper solves an approximate form of conservation of mass and momentum for a turbine in a wind farm array. The solution is a fairly simple explicit relationship that predicts t…
Wake steering of multirotor wind turbines
Gustav A. Speakman, Mahdi Abkar, Luis A. Martínez-Tossas +1
In this paper, wake steering is applied to multirotor turbines to determine whether it has the potential to reduce wind plant wake losses. Through application of rotor yaw to multi…
