Improvements to the dynamic wake meandering model by incorporating the turbulent Schmidt number
Fernando Porté Agel, Peter Andreas Brugger, Corey Dean Markfort
Predictions of the dynamic wake meandering model (DWMM) were compared to flow measurements of a scanning Doppler lidar mounted on the nacelle of a utility-scale wind turbine. We observed that the wake meandering strength of the DWMM agrees better with the ...
2024An improved statistical wake meandering model
Fernando Porté Agel, Peter Andreas Brugger, Corey Dean Markfort
A new statistical wake meandering (SWM) model is proposed that improves on existing models in the literature. Compared to the existing SWM models, the proposed model has a closed description that does not require simulations to create look-up tables while ...
IOP Publishing2024Holistic scan optimization of nacelle-mounted lidars for inflow and wake characterization at the RAAW and AWAKEN field campaigns
Fernando Porté Agel, Peter Andreas Brugger
In this article, we provide a methodological framework for designing the scanning strategies of nacelle-mounted scanning lidars for wind energy field experiments, and apply it at two major experimental field campaigns. For the Rotor Aerodynamics, Aeroelast ...
IOP PUBLISHING LTD2023Characterization of wind turbine flow through nacelle-mounted lidars: a review
Fernando Porté Agel, Peter Andreas Brugger
This article provides a comprehensive review of the most recent advances in the planning, execution, and analysis of inflow and wake measurements from nacelle-mounted wind Doppler lidars. Lidars installed on top of wind turbines provide a holistic view of ...
2023Including the turbulent Schmidt number in the dynamic wake meandering model
Fernando Porté Agel, Peter Andreas Brugger, Corey Dean Markfort
Wind turbine wakes are an important source of power losses and mechanical wear within wind farms. Wake meandering is a low-frequency oscillation of the entire wind turbine wake with respect to the time-averaged centerline. It affects power losses by contri ...
2023Options to correct local turbulent flux measurements for large-scale fluxes using an approach based on large-eddy simulation
The eddy-covariance method provides the most direct estimates for fluxes between ecosystems and the atmosphere. However, dispersive fluxes can occur in the presence of secondary circulations, which can inherently not be captured by such single-tower measur ...
2021Lidar measurements of yawed-wind-turbine wakes: characterization and validation of analytical models
Fernando Porté Agel, Peter Andreas Brugger, Haohua Zong
Wake measurements of a scanning Doppler lidar mounted on the nacelle of a full-scale wind turbine during a wake-steering experiment were used for the characterization of the wake flow, the evaluation of the wake-steering set-up, and the validation of analy ...
2020Characterization of Wind Turbine Wakes with Nacelle-Mounted Doppler LiDARs and Model Validation in the Presence of Wind Veer
Fernando Porté Agel, Peter Andreas Brugger, Corey Dean Markfort, Fernando Carbajo Fuertes, Mohsen Vahidzadeh
Accurate prediction of wind turbine wakes is important for more efficient design and operation of wind parks. Volumetric wake measurements of nacelle-mounted Doppler lidars are used to characterize the wake of a full-scale wind turbine and to validate an a ...
2019Preliminary evidence for a fronto-parietal dysfunction in able-bodied participants with a desire for limb amputation
Olaf Blanke, Peter Andreas Brugger
BACKGROUND: Reports of able-bodied participants with the persisting desire for limb amputation raise legal and ethical questions that are partly due to insufficient empirical knowledge about the condition. Here, we searched for potential neurological mecha ...
British Psychological Society2009Polyopic heautoscopy: Case report and review of the literature
Olaf Blanke, Peter Andreas Brugger
Heautoscopy, i.e., the encounter with one's double, is a multimodal illusory reduplication of one's own body and self. In its polyopic form, more than one double is experienced. In the present article, we review fourteen published cases of polyopic heautos ...
