Unsteady aerodynamic response of pitching airfoils represented by Gaussian body forces

Emanuel Taschner, Georgios Deskos, Michael B. Kuhn +2

The actuator line method (ALM) is an approach commonly used to represent lifting and dragging devices like wings and blades in large-eddy simulations (LES). The crux of the ALM is…

Ensemble-based, large-eddy reconstruction of wind turbine inflow in a near-stationary atmospheric boundary layer through generative artificial intelligence

Alex Rybchuk, Luis A. Martínez-Tossas, Stefano Letizia +7

To validate the second-by-second dynamics of turbines in field experiments, it is necessary to accurately reconstruct the winds going into the turbine. Current time-resolved inflow…

Ensemble flow reconstruction in the atmospheric boundary layer from spatially limited measurements through latent diffusion models

Alex Rybchuk, Malik Hassanaly, Nicholas Hamilton +3

Due to costs and practical constraints, field campaigns in the atmospheric boundary layer typically only measure a fraction of the atmospheric volume of interest. Machine learning…

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…

Mechanisms of dynamic near-wake modulation of a utility-scale wind turbine

Aliza Abraham, Luis A. Martinez-Tossas, Jiarong Hong

The current study uses large eddy simulations to investigate the transient response of a utility-scale wind turbine wake to dynamic changes in atmospheric and operational condition…

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…

Wake Structure of Wind Turbines in Yaw under Uniform Inflow Conditions

Michael F. Howland, Juliaan Bossuyt, Luis A. Martinez-Tossas +2

Reducing wake losses in wind farms by deflecting the wakes through turbine yawing has been shown to be a feasible wind farm controls approach. Nonetheless, the effectiveness of yaw…

Optimal smoothing length scale for actuator line models of wind turbine blades

Luis A. Martinez-Tossas, Matthew J. Churchfield, Charles Meneveau

The actuator line model (ALM) is a commonly used method to represent lifting surfaces such as wind turbine blades within Large-Eddy Simulations (LES). In the ALM the lift and drag…
