Development of wake meandering detection algorithms and their application to large eddy simulations of an isolated wind turbine and a wind farm

We investigate several algorithms to detect the centerline of a wind turbine wake. First, we apply these methods during Large Eddy Simulations of an isolated wind turbine subject to a uniform (TI = 0%) and a synthetic turbulent inflow (TI = 10%). The simulations are performed using a vortex-particle...

Summary:We investigate several algorithms to detect the centerline of a wind turbine wake. First, we apply these methods during Large Eddy Simulations of an isolated wind turbine subject to a uniform (TI = 0%) and a synthetic turbulent inflow (TI = 10%). The simulations are performed using a vortex-particle mesh method with the blades modeled using immersed lifting lines. The most robust algorithm is then applied to investigate the wakes positions inside a wind farm. At wind farm scale, the simulations are performed with a fourth-order finite difference code inside which the wind turbines are accounted for through advanced actuator disks.
