论文摘要
跨流涡轮机,也称为垂直轴涡轮机,使用叶片旋转垂直于传入流的轴旋转的叶片将动流量转换为机械能。在这项工作中,在六十四个独特的阵列配置中对循环水通道中两涡轮的性能进行了实验优化。对于每种配置,使用尖端速度比控制优化了涡轮机性能,其中每个涡轮机的旋转速率单独优化,并使用协调的控制,在该控制器中,在该控制器中优化了涡轮机以在同步旋转速率下运行,但相差。对于每种配置和控制策略,还评估了共旋转和反旋转的后果。我们假设阵列配置和控制案例如何影响涡轮机之间的相互作用与影响阵列性能之间的相互作用。
Cross-flow turbines, also known as vertical-axis turbines, convert the kinetic energy in moving fluid to mechanical energy using blades that rotate about an axis perpendicular to the incoming flow. In this work, the performance of a two-turbine array in a recirculating water channel was experimentally optimized across sixty-four unique array configurations. For each configuration, turbine performance was optimized using tip-speed ratio control, where the rotation rate for each turbine is optimized individually, and using coordinated control, where the turbines are optimized to operate at synchronous rotation rates, but with a phase difference. For each configuration and control strategy, the consequences of co- and counter-rotation were also evaluated. We hypothesize how array configurations and control cases influence interactions between turbines and impact array performance.
