论文摘要
在这里，我们研究了介电屏障放电（DBD）血浆执行器的使用，以改善海上6MW风力涡轮机的空气动力学性能。通过控制不同叶片部分的空气动力负载，可以改善总体产生的功率和刀片负载。刀片分为七个段，分析应用于每个段。为了研究配置和位置的效果，在不同的和弦的位置将执行器安装在单个或串联配置中，分布在跨度长度的46％至56％之间。作者开发的改进的现象学模型用于模拟静电场，电离颗粒和流体流的相互作用。使用数值模拟预测的每个截面的空气动力系数，估算了生成的功率。我们研究了单个和串联执行器的位置和配置如何提高95kW的生成功率。另外，我们研究了使用集体俯仰角的可能性。它表明，以10度的集体音高角度，在6和10 m/s的风速下，一个可以分别收获10.03％或11.42％的能量。在研究的七个案例中，靠近前沿的执行器的表现比其他案例更好。
Here we have investigated the usage of a Dielectric Barrier Discharge (DBD) plasma actuator to improve the aerodynamic performance of an offshore 6MW wind turbine. By controlling the aerodynamic load at different blade sections, the overall generated power and the blade loading is improved. The blade is divided to seven segments and the analysis is applied to each segment. To study effects of configuration and location, actuators were installed in a single or tandem configuration, spread between 46% and 56% of the span length, at different chord wise locations. The improved phenomenological model developed by authors were used to simulate the interaction of the electrostatic field, the ionized particles and the fluid flow. Using the aerodynamic coefficients of each section predicted by numerical simulation, the generated power was estimated. We investigated how the location and configuration of the single and tandem actuators improve the generated power up to 95kW. Also, we studied possibility of using collective pitch angles. It showed that with a collective pitch angle of 10 degrees, one may harvest 10.03% or 11.42% more energy at wind speeds of 6 and 10 m/s respectively. Among seven cases studied, actuators closer to the leading edge performed better than others.
