摘 要随着我们的生活水平不断的进步发展，需求量的增大让我们对海洋的探究越发的深入，其中海洋流中的多种优势使其成为最重要的海洋资源之一。在国外的震荡浮子式波浪能装置已经趋于成熟，而国内的研究尚处于初始阶段。我们所熟知很多因素会影响装置的效率转化，在此次研究中我们将对不同流速下浮子对立柱涡流运动的影响进行深度探究，主要通过测量不同流速下均匀流中有无浮子对立柱的横向力，表面压力，阻力升力等数据的整理分析以及对流场的测量，来体现不同流速时浮子对立柱涡流运动的影响。利用相似准则，按比例用模型代替实物制定实验方案，最后对比实验得到的数值和理论分析得出的数值，结果一致进一步验证了理论分析的正确性。77117

Abstract With the development of our living standards，the increase of demand enables us to explore more in-depth for the sea。 Waves can be a variety of advantages that makes it one of the most important Marine resources。 The oscillation of the abroad float type wave energy device has been mature, but domestic research is still in its initial stage。 We know a lot of factors will affect the efficiency of unit conversion, In this study we will float to columns under different flow velocity with depth of investigation on the influence of vortex motion, Mainly by measuring the uniform flow under different flow rate in the presence of float to the pillar of the transverse force, surface pressure, wave analysis and the higher data flow field measurement to reflect the influence of different velocity when the float of pillar eddy motion。 Using the similarity criterion in proportion to substitute model for physical experiment plan formulation。 Finally, comparative experiments of numerical value and theoretical analysis , results further validate the correctness of theoretical analysis。
This paper mainly complete the following aspects of work：
1、Through application of contact with the school laboratory equipment, learned the composition of the experimental apparatus, operating mode to develop experimental scheme to establish experimental program began experimenting。
2、Measure five kinds of velocity pillar under the presence of float in the uniform flow, measuring and recording, drawing curve image。
3、Comparison between the numerical simulation and experimental simulations verify the correctness。
