In the booming sector of tidal and hydrokinetic energy, Canada is playing a leading role with its demonstrator and technology incubator test sites. It is also quite active in the development and design of innovative hydrokinetic turbine concepts among which the Oscillating-Wings Turbine (OWT) technology is quite promising. Better adapted to shallow water sites than most other technologies, it offers high energy extraction efficiency while using very simple untwisted rectangular hydrofoils. In tandem or parallel configurations, the hydrofoils are made to oscillate up and down in a vertical plane when submerged in a water current.This research program is based on computational fluid dynamic (CFD) studies and involves six specific projects. It takes great advantage of the supercomputer infrastructures of Compute Canada and aims to provide essential hydrodynamic data in support of the OWT technology. Efficiency optimization of the turbine design and of its operating parameters is sought as well as proper hydrodynamic guidelines for its efficient deployment. This includes the important effects of perturbed, real water flow conditions and free-surface effects one might expect in rivers and in tidal estuaries. Hydrodynamic issues related to the deployment of multi-units arrays are also addressed such as turbines interference and blockage effects. At least 6 graduate students will be trained and contribute to this research as well as 5 undergraduate research assistants. Making OWTs and their exploitation more efficient makes this energy source more attractive from an economical point of view. Doing so, this research thus promotes the growth of a new sustainable, eco-friendly energy production source for Canada and the emergence of an innovative technology with great export potential.

在蓬勃发展的潮汐能和水力能源领域，加拿大凭借其示范和技术孵化器测试场发挥着主导作用。该公司在创新水力涡轮机概念的开发和设计方面也非常活跃，其中摆动翼涡轮机（OWT）技术非常有前途。与大多数其他技术相比，它更适合浅水场所，在使用非常简单的无扭曲矩形水翼的同时提供高能量提取效率。在串联或并联配置中，水翼浸没在水流中时会在垂直平面内上下振荡。该研究计划基于计算流体动力学 (CFD) 研究，涉及六个具体项目。它充分利用了加拿大计算局的超级计算机基础设施，旨在提供必要的流体动力学数据来支持 OWT 技术。寻求涡轮机设计及其运行参数的效率优化以及对其有效部署的适当的水动力指南。这包括河流和潮汐河口中可能出现的扰动、真实水流条件和自由表面效应的重要影响。还解决了与多单元阵列部署相关的水动力问题，例如涡轮机干扰和阻塞效应。至少 6 名研究生以及 5 名本科生研究助理将接受培训并为这项研究做出贡献。从经济角度来看，提高 OWT 及其开发效率使得这种能源更具吸引力。因此，这项研究促进了加拿大新的可持续、环保能源生产来源的增长，以及具有巨大出口潜力的创新技术的出现。
