为了研究矩形潮流能水轮机的性能,设计了矩形潮流能水轮机及其实验模型装置,构建了实验平台,选配了实验仪器和设备,进行矩形潮流能水轮机模型的往复流及变安装摆角实验、密实度影响实验和不同流速下的功率输出实验.实验结果表明:矩形水轮机具有良好的双向来流单向旋转特性,在来流速度大小恒定的情况下,正向来流和反向来流具有相同的能量捕获能力;当安装摆角ψ=±15°时,水轮机的能量捕获能力优于ψ=±5°时的;不同速比区间内,随密实度增加,水轮机的获能能力也相应增加;流速增加,输出功率峰值增大,峰值点右移.
In order to study the performance of rectangular tidal current turbine, a rectangular tidal current turbine and its experimental model device were designed. An experimental platform was built, and experimental equipment and equipment were selected. Reciprocating flow and variable mounting swivel angle test of rectangular tidal current turbine were carried out. Density experiments and power output experiments under different flow velocities.The experimental results show that the rectangular hydro turbine has a good one-way rotation characteristics of two-way flow, and when the flow velocity is constant, the forward flow and the reverse flow have the same When the swing angle ψ = ± 15 °, the energy capture ability of the turbine is better than ψ = ± 5 °. In different speed ratios, the capacity of the turbine increases with the increase of the compactness. The flow rate increases, the peak output power increases, the peak shifts to the right.
