In the case of flooding in rivers, river regulation structures are important since scours occur on the outer meander due to high flow velocities. In this study, 2-array submerged vane structures were investigated which is a new method in the meandering part of open channels, both laboratory and numerically with an open channel flow discharge of 20 L/s. Open channel flow experiments were carried out by using a submerged vane and without a vane. The flow velocity results of the computational fluid dynamics (CFD) models were compared to the experimental results and the results were found compatible. The flow velocities were investigated along with depth using the CFD and found that the maximum velocity was reduced by 22-27% along the depth. In the outer meander, the 2-array submerged vane with a 6-vane structure was found to affect the flow velocity by 26-29% in the region behind the vane.
在河流洪水的情况下，由于高流速，外部弯道会发生冲刷，因此河道调节结构非常重要。本研究中，对 2 排淹没式叶片结构进行了研究，这是明渠弯道部分的一种新方法，通过流量为 20 L/s 的明渠进行了实验室和数值研究。通过使用淹没式叶片和不使用叶片进行了明渠水流实验。将计算流体动力学（CFD）模型的流速结果与实验结果进行了比较，结果发现两者吻合较好。通过 CFD 研究了沿深度的流速，并发现最大流速沿深度降低了 22-27%。在外弯道中，发现具有 6 个叶片结构的 2 排淹没式叶片在叶片后方区域对流速的影响为 26-29%。
