【摘要】：基于FLOW-3D軟件平臺(tái)建立三維水動(dòng)力計(jì)算模型,研究水輪機(jī)橫向間距、相對(duì)安裝高度和來流速度對(duì)二臺(tái)并排布置的水平軸潮流能水輪機(jī)組的水動(dòng)力特性的影響。結(jié)果表明:隨著橫向間距的增大,水輪機(jī)組受到的與來流方向相同的最大水流作用力有一定減小,最大降幅達(dá)6.62%,尾流場(chǎng)中水流加速區(qū)域的最大流速也略有減小,最大降幅約1.21%;水輪機(jī)組相對(duì)安裝高度和來流速度的改變,對(duì)其飛逸轉(zhuǎn)速、最大水流作用力以及尾流場(chǎng)有顯著影響。
[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.
