【摘要】：基于FLOW-3D软件平台建立三维水动力计算模型,研究水轮机横向间距、相对安装高度和来流速度对二台并排布置的水平轴潮流能水轮机组的水动力特性的影响。结果表明:随着横向间距的增大,水轮机组受到的与来流方向相同的最大水流作用力有一定减小,最大降幅达6.62%,尾流场中水流加速区域的最大流速也略有减小,最大降幅约1.21%;水轮机组相对安装高度和来流速度的改变,对其飞逸转速、最大水流作用力以及尾流场有显著影响。
[Abstract]:Based on the FLOW-3D software platform, a three-dimensional hydrodynamic calculation model is established, and the horizontal spacing of the turbine is studied. The influence of relative installation height and flow velocity on the hydrodynamic characteristics of two horizontal axis tidal current turbine sets arranged side by side. The results show that: with the increase of transverse spacing, The maximum flow force in the same direction as the flow direction of the turbine group decreases to a certain extent, the maximum drop reaches 6.62 and the maximum velocity of the flow in the wake field decreases slightly. The maximum drop is about 1.21 and the changes of the relative installation height and the incoming flow velocity of the turbine group have a significant effect on the flight speed the maximum flow force and the wake flow field.
