EAPSI: Maximizing the Velocity of Incoming Ocean Waves with Wave-Enhancing Resonance Chambers for Increased Energy Production

海浪能将是未来重要的能源来源。研究表明，利用共振室可以提高波浪中的速度，从而增加从波能涡轮收割机中提取的电量。与噪音回响和增加的方式相同，当海浪传播到狭窄进水口末端一定体积的盆地时，海浪也会增加。这些更大的海浪有更大的速度，可以更快地驱动电动涡轮机，增加来自相同资源的电力输出。波浪涡轮机通常是成组部署的。涡轮机的布置会影响流体的流动。该奖项支持在一个能源场中部署多个涡轮机时，确定腔室的理想布置的研究。这项研究将与斯温本理工大学的理查德·马纳塞教授合作进行，他是海浪发电机阵列领域的领先研究员。夏威夷大学PI的研究表明，亥姆霍兹谐振器可以用来增加从海浪中提取的流体速度和能量。在波能应用中利用共振室是相当新颖的，也是优化波能技术的自然下一步。下一步是将这些谐振器应用于波浪场的平行阵列类型，以确定如何优化波浪机的效率。一系列的模拟将在斯温本波浪水箱的三个舱中进行。将运行模拟，其中所有三个阵列具有相同的维度，并且维度也不同。成功的测试将随着模式的出现而得到改进。该NSF EAPSI奖是与澳大利亚科学院合作资助的。

Ocean wave energy will be a critical energy source in the future. It has been shown that velocity in waves can be increased with resonance chambers, increasing the amount of electricity that can be extracted from wave energy turbine harvesters. In the same way that noise reverberates and increases, ocean waves increase when they propagate into a basin of a certain volume at the end of a narrow inlet. These bigger ocean waves have a greater velocity which can turn electric turbines faster, increasing the electricity output from the same resources. Wave turbines are usually deployed in groups. The arrangement of turbines affects fluid flow. This award support research that will determine the ideal arrangement of chambers, when multiple turbines are deployed in an energy farm. This research will be conducted in collaboration with Professor Richard Manasseh at Swinburne University of Technology, a leading researcher in the area of arrays of ocean wave power machines. Research by the PI at the University of Hawai'i has shown that Helmholtz resonators can be used to increase the fluid velocity and energy extracted from ocean waves. Utilization of resonance chambers in wave-energy applications is fairly novel and a natural next step in optimizing wave energy technologies. The next step is to apply these resonators to the type of parallel arrays of wave farms, to determine how to optimize efficiency in wave machines. A series of simulations will be run on three chambers in the Swinburne wave tank. Simulations will be run in which all three arrays have the same dimensions, and also varying the dimensions. Successful tests will be refined as patterns emerge. This NSF EAPSI award is funded in collaboration with the Australian Academy of Science.
