Improvements to the dynamic wake meandering model by incorporating the turbulent Schmidt number

Fernando Porté Agel, Corey Dean Markfort, Peter Andreas Brugger

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 ...

An improved statistical wake meandering model

Fernando Porté Agel, Corey Dean Markfort, Peter Andreas Brugger

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 ...

Overview of preparation for the American WAKE ExperimeNt (AWAKEN)

Fernando Porté Agel, Peter Andreas Brugger

The American WAKE ExperimeNt (AWAKEN) is a multi-institutional field campaign focused on gathering critical observations of wind farm-atmosphere interactions. These interactions are responsible for a large portion of the uncertainty in wind plant modeling ...

Holistic 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 ...

Characterization 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 ...

Field measurements of wake meandering at a utility-scale wind turbine with nacelle-mounted Doppler lidars

Fernando Porté Agel, Peter Andreas Brugger

Wake meandering is a low-frequency oscillation of the entire wind turbine wake that can contribute to power and load fluctuations of downstream turbines in wind farms. Field measurements of two Doppler lidars mounted on the nacelle of a utility-scale wind ...

Lidar 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 ...

Characterization of Wind Turbine Wakes with Nacelle-Mounted Doppler LiDARs and Model Validation in the Presence of Wind Veer

Fernando Porté Agel, Fernando Carbajo Fuertes, Corey Dean Markfort, Mohsen Vahidzadeh, Peter Andreas Brugger

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 ...

Preliminary 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 ...

Polyopic 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 ...

Perceptual aberrations impair mental own-body transformations

Olaf Blanke, Christine Mohr, Peter Andreas Brugger

Dysfunctional self and bodily processing have been reported from the schizophrenia spectrum. Here, the authors tested 72 students (40 women) to determine whether performance in a mental own-body transformation task relates to self-rated frequency of sponta ...

Linking out-of-body experience and self processing to mental own-body imagery at the temporoparietal junction

Olaf Blanke, Christine Mohr, Peter Andreas Brugger

The spatial unity of self and body is challenged by various philosophical considerations and several phenomena, perhaps most notoriously the "out-of-body experience" (OBE) during which one's visual perspective and one's self are experienced to have departe ...
