Numerical Modeling of Multiple Hydrokinetic Turbines

这项工作的目的是研究多种水动力河流涡轮机的性能，清洁能源技术**提供了取代柴油发电的机会，特别是在偏远地区。这项工作支持《海洋能源路线图》，以实现海洋技术的市场渗透，并与《气候领导计划》一致，以更清洁的能源取代燃煤发电。当多台涡轮机排成一排时，上游发展的尾迹将显著影响下游涡轮机的性能。涡轮的几何复杂性、相对运动中旋转部件的存在、下游区域复杂的湍流尾迹-结构相互作用，限制了现有的低保真商用数值工具的应用，需要高保真的数值方法。为了提高**系统的性能，解决**这些限制对新能源公司至关重要。利用CFSMgroup开发的高保真稳定和多尺度方法，计算流体动力学（CFD）模拟将对新能源公司设计的多台全尺寸25kw垂直涡轮机进行**，以研究**不同配置和实际流动条件下多台涡轮机周围的流动行为。

This work aims to investigate the performance of multiple hydrokinetic river turbines, clean energy technology**that provides opportunities to displace diesel generation especially in a remote regions. This work supports**Marine Energy Roadmap to achieve market penetration for marine technology and aligns with Climate**Leadership Plan to replace coal-fired electricity generation with cleaner energy sources. When multiple**turbines are arranged in a row the wake developed upstream will significantly affect the performance of the**downstream turbines. The geometric complexity of the turbine, presence of the rotating components in a**relative motion, complex turbulent wake-structure interaction in a downstream region limits the application of**existing low-fidelity commercial numerical tools and requires high-fidelity numerical methods. Addressing**these limitations is of major importance to New Energy Corporation in order to improve the performance of the**system. Using high-fidelity stabilized and multi-scale methods developed by CFSMgroup the computational**fluid dynamics (CFD) simulations will be performed on a multiple full-scale 25-kW vertical turbines designed**by New Energy to investigate the flow behaviour around multiple turbines in different configurations and under**the realistic flow conditions.
