Prediction of multi-wake problems using an improved Jensen wake model

, 2017
The improved analytical wake model named as 2D_k Jensen model (which was proposed to overcome some shortcomes in the classical Jensen wake model) is applied and validated in this work for wind turbine multi-wake predictions.

Vortex-induced vibration of catenary riser: reduced-order modeling and lock-in analysis using wake oscillator

, 2009
A new reduced-order model capable of analyzing the vortex-induced vibration of catenary riser in the ocean current has been developed. This semi analytical-numerical approach is versatile and allows for a significant reduction in computational effort for

FLOWERS AEP: An Analytical Model for Wind Farm Layout Optimization

Wind Energy
Annual energy production (AEP) is commonly used in objective functions for wind farm layout optimization. AEP is proportional to wind farm power production integrated over an annual distribution of free‐stream wind conditions.

Volumetric LiDAR scanning of a wind turbine wake and comparison with a 3D analytical wake model

A correct estimation of the future power production is of capital importance whenever the feasibility of a future wind farm is being studied. This power estimation relies mostly on three aspects: (1) a reliable measurement of the wind resource in the ...

Experimental analysis of analytical wake models for wind turbines

, 2017
In a cluster of wind turbines, the interference between wind turbines affect negatively. Upstream wind turbines generate wakes where the velocity is reduced and the turbulence increased.
