  • AMT - Three-dimensional structure of wind turbine

    Three-dimensional structure of wind turbine wakes as measured by scanning lidar. Abstract. The lower wind speeds and increased turbulence that are characteristic of turbine wakes have considerable consequences on large wind farms: turbines located downwind generate less power and experience increased turbulent loads.

  • WES - The curled wake model: a three-dimensional

    Abstract. Wind turbine wake models typically require approximations, such as wake superposition and deflection models, to accurately describe wake physics. However, capturing the phenomena of interest, such as the curled wake and interaction of multiple wakes, in wind power plant flows comes with an increased computational cost.

    Purpose: Subject motion is a major source of image degradation for functional MRI (fMRI), especially when using multishot sequences like three-dimensional (3D EPI). We present a hybrid radial-Cartesian 3D EPI trajectory enabling motion correction in k-space for functional MRI. Methods: The EPI 'blades' of the 3D hybrid radial-Cartesian EPI sequence, called TURBINE, are rotated about the phase ...
