説明
<p>A 2D numerical study is conducted to assess the effect of outer stators on the performance of a vertical wind turbine and the acoustical noise radiation. The model wind turbine is 3 straight blades Giromill type with a NACA 0015 airfoil. The stators are composed of 4 straight plates. The flow interaction mechanism between the turbine blades and the stator blades and the acoustic characteristics are analyzed applying the finite difference lattice Boltzmann method. From the results, it is observed that the increase of the incident flow velocity guided by the stator blades increases the rotor blade lift at a certain azimuth angle interval. The cycle averaged torque coefficient of the turbine with the stators is greater by maximum 40% compared to the no stator turbine. The mean sound pressure observed at a distance of 10m from the center around the turbine with the stators is 1.5 times i.e. 3.5 dB larger compared to the pressure of the no stator turbine.</p>
