【摘要】：随着地球生态环境的破坏程度日益增加,化石燃料能源的逐渐枯竭,迫切需要新的能源来支撑人类社会的运转。世界各国把目光投到了海洋,海洋面积占地球的70%,其拥有丰富的各类资源,不仅有石油、天然气、可燃冰等,还蕴藏着巨大的、洁净的、可再生的海洋能源。波浪能作为海洋能源的典型代表,又可通过一定的装置提取到丰富的绿色能源,因而倍受世界各国的关注和重视。人类对波浪能的研究已有一百多年的历史。目前,利用波浪能发电的技术已经有了突破性的进展,已经从初步的研究与模型实验走向了研制简单小型的海洋波浪能装置从海洋中提取波浪能源。本文根据现有的波浪能发电理论和技术,设计了一种新型波浪能发电装置,即漂浮式直驱波浪能发电装置。本文对漂浮式直驱波浪能发电装置进行了设计,部件选型,对叶片水动力性能和锚泊系统的仿真分析,制作样机并做了水槽试验,本文的研究成果如下:(1)根据海洋波浪运动理论,本论文首先确定了漂浮式直驱波浪能发电装置的设计原则及工作原理,介绍了将要用到的相关基础理论。(2)根据相关基础理论和波浪能发电装置工作的要求,本论文确定了漂浮式直驱波浪能发电装置的设计方案,确定了装置的结构组成,对主要部件根据实际需要进行了定制选取。(3)根据设计确定的装置叶片尺寸,等比例建立模型,运用流体力学分析软件Fluent和AQWA系统对其进行了水动力性能分析,并分析了流速、转数对其水动力性能的影响。(4)制造了小型样机,并且在水槽中做了实验,结合Fluent流体分析,对装置进行优化设计,验证了装置的可行性及流体分析的正确性。
[Abstract]:With the increasing destruction of the earth's ecological environment and the gradual depletion of fossil fuel energy, new energy sources are urgently needed to support the operation of human society. Countries all over the world have focused their attention on the ocean, which occupies 70% of the earth. It has abundant resources, not only oil, natural gas, flammable ice, but also huge, clean and renewable marine energy. Wave energy, as a typical representative of ocean energy, can also be extracted from abundant green energy by a certain device, so it has attracted the attention and attention of many countries all over the world. Man has studied wave energy for more than one hundred years. At present, the technology of using wave energy to generate electricity has made a breakthrough, and has moved from preliminary research and model experiments to the development of a simple and small ocean wave energy device to extract wave energy from the ocean. According to the existing wave energy generation theory and technology, a new wave energy generating device, floating direct-drive wave energy generator, is designed in this paper. In this paper, the floating-type direct-drive wave power generation device is designed, the components are selected, the hydrodynamic performance of the blade and the mooring system are simulated, the prototype is made and the flume test is done. The results of this paper are as follows: (1) according to the theory of ocean wave motion, the design principle and working principle of floating direct-drive wave energy generator are first determined in this paper. This paper introduces the relevant basic theories to be used. (2) according to the relevant basic theories and the requirements of wave power generation equipment, this paper determines the design scheme of floating direct-drive wave power generation device, and determines the structure of the device. The main components are customized and selected according to the actual needs. (3) according to the design of the device blade size, equal proportion of the model, hydrodynamic analysis software Fluent and AQWA system were used to analyze its hydrodynamic performance, and the velocity of flow was analyzed. (4) A small prototype was made, and the experiment was done in the flume. The Fluent fluid analysis was used to optimize the design of the device, which verified the feasibility of the device and the correctness of the fluid analysis.
