A Fully Three-Dimensional Turbulent Method for the Analysis of Horizontal-Axis Wind Turbines in Wind Farms

摘要

Computational Fluid Dynamics (CFD) is a promising tool for the analysis and optimization of the wind turbines positioning inside a wind park. In the present work, the three-dimensional, time-averaged, steady-state, incompressible Navier-Stokes equations, in which the wind turbines are represented by momentum sources, are solved using a Control-Volume Finite Element Method (CVFEM). The authors' previous works demonstrated the accuracy of this approach for isolated wind turbine power predictions. The capabilities of the proposed method to predict wind turbine wake characteristics are illustrated. Results for the MOD-OA wind turbine in neutral atmospheric boundary layers are presented and a periodic wind farm arrangement composed of two rows of turbines is studied. Satisfactory agreement with experimental measurements is achieved, and qualitative agreement with observations is obtained for gross wake characteristics.
