Study on the Influence of the Operation of Multiple Wind Turbines on the Turbulent Kinetic Energy in the Atmospheric Boundary Layer

摘要

By analyzing the potential influence of the operation of multiple wind turbines on the surface boundary layer was studied. Gambit software was used to establish multiple wind turbine and wind field model, and the Fluent software was used to simulate the flow of four sets of wind turbine in parallel and stagger arrangement. Results show that The turbulence kinetic energy in the near-ground boundary layer is affected by the operation of the wind turbine. The variation rule of the turbulent kinetic energy at different heights and downstream distances is different. Along the vertical direction of the upper part of the wind turbine, The turbulence kinetic energy decreases gradually along the flow direction, and the turbulence kinetic energy of the staggered column arrangement is higher than that of the same row arrangement arrangement as a whole.
