摘要
针对可变翼装置导叶的简化模型设计试验;然后,分别考察波浪与旋转到叶轮不同位置处导叶的相互作用过程,明确波浪作用下导叶的摆动规律及不同位置处导叶对叶轮转动的贡献;最后,提出以导叶所受水平波浪荷载为目标的提高装置捕能效率的方法,并通过前期研究成果进行验证。通过试验研究发现,在波浪传播方向上转动到旋转轴位于导叶后方时的导叶对叶轮的转动起控制作用,此处的导叶在摆动过程中波谷时刻导叶所受水平波浪荷载由负向变为零,以导叶所受水平波浪荷载为目标的提高装置捕能效率的研究方法能较准确地给出装置捕能效率的改变效果。
Firstly,a wave flume experiments are conduct on a simplified guide vane model.Then,the movements of the guide vane at different positions during the rotation of the guide vane wheel are investigated,and the rotation rule and the contribution to the guide vane wheel rotation of the guide vanes at different positions are specified.At last,a new method for improving the energy capture efficiency of the device targeting the horizontal wave force on the guide vane is proposed and validated by previous research results.It is observed that the rotation of the guide vane wheel is controlled by the guide vane ahead the guide vane axis,and the guide vane at this position receives a horizontal wave force from negative to zero at the moment of wave trough.The method for improving the energy capture efficiency of the device targeting the horizontal wave force on the guide vane can accurately give the change in the energy capture efficiency of the device.
