双双击式水轮机阵列的几何和控制优化

Geometric and Control Optimization of a Two Cross-Flow Turbine Array

Isabel Scherl, Benjamin Strom, Steven L. Brunton, Brian L. Polagye

摘要:

双击式水轮机,也称为垂直轴涡轮机,使用围绕垂直于进入流的轴线旋转的叶片将移动流体中的动能转换为机械能。在这项工作中,在循环水通道中的两个涡轮阵列的性能进行了实验优化,在64个独特的阵列配置。对于每种配置,使用叶尖速比控制和协调控制来优化涡轮机性能,其中叶尖速比控制单独优化每个涡轮机的转速,协调控制优化涡轮机以同步转速运行,但具有相位差。对于每种配置和控制策略,还评估了共同旋转和反向旋转的后果。我们假设阵列配置和控制情况如何影响涡轮机之间的相互作用和影响阵列性能。

英文摘要:

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.
