Wave energy from a shear resource magnitude perspective is a very promising low-GHG energy source that**can potentially play a role in Canada's evolving energy mix for both grid-connected and remote coastal**communities. Wave energy converters (WECs) which must transform raw wave energy into useful electrical**power face the key challenge of power density; that is how many kW of power can be generated per kg of**device mass. As WEC cost is to a large degree proportional to mass, improving this power density can greatly**impact the economics of WECs.**The proposed project is aimed at helping the developers, Blu-tility, of a novel attenuator type WEC named the**Blu-Dino System, to improve the simulation fidelity of their system and optimize the key system parameters**for wave conditions on Canada's West Coast. The Blu-Dino WEC concept utilizes a helical attenuator design,**and which holds up the promise of greatly improved power density. Novel CFD methods developed at UVic**will be employed to analyse the hydrodynamics of the device, to compare again simplified hydrodynamic**models that may miss some important viscous hydrodynamic effects. A heuristic optimization framework,**developed previously for other WEC types and floating offshore wind turbine structures, will be used to refine**the system design. The output of the project will be better insight into the Blu-Dino system design parameters,**and a toolset for continued development of a prototype.

从剪切资源量的角度来看，波浪能是一种非常有前途的低温室气体能源，** 可能在加拿大不断发展的能源组合中发挥作用，为电网连接和偏远的沿海 ** 社区。波浪能转换器（WEC）必须将原始波浪能转换为有用的电功率，它面临着功率密度的关键挑战;也就是说，每公斤设备质量可以产生多少千瓦的功率。由于WEC成本在很大程度上与质量成正比，因此提高功率密度可以极大地 ** 影响WEC的经济性。该项目旨在帮助开发商Blu-tility开发一种名为 **Blu-Dino系统的新型衰减器型WEC，以提高其系统的模拟保真度，并针对加拿大西海岸的波浪条件优化关键系统参数 **。Blu-Dino WEC概念采用螺旋衰减器设计，** 并承诺大大提高功率密度。UVic** 开发的新型CFD方法将用于分析器械的流体动力学，再次比较可能遗漏一些重要粘性流体动力学效应的简化流体动力学 ** 模型。一个启发式优化框架，** 以前开发的其他类型的WEC和浮动海上风力涡轮机结构，将用于完善 ** 系统设计。该项目的产出将是更好地了解Blu-Dino系统设计参数，** 和一个用于继续开发原型的工具集。
