Unsteady Fluid Dynamics of Tidal Stream Turbines

潮汐能是一种很大程度上尚未开发的可再生能源，具有能源供应可预测性的优点。潮汐环境非常恶劣，波浪和湍流对涡轮机产生巨大的非定常负荷，可能导致设备故障和设备设计过于保守。与工业伙伴合作，该学生将使用计算流体动力学建模以及实验室规模的涡轮实验来了解非定常流动，波浪和湍流如何发展非定常转子加载，以及如何将这种加载纳入工程设计工具。

Tidal stream energy offers a largely unexploited renewable energy source with the benefit of predictability of energy supply. Tidal environments are extremely harsh with waves and turbulence producing large unsteady loads on turbines that can re-sult in device failure and over-conservatism in device design. Working with industri-al partners this studentship will use Computational Fluid Dynamics modelling as well as laboratory scale turbine experiments to understand how unsteady flows, waves and turbulence develop unsteady rotor loading, and how this loading can be incorporated in engineering design tools.
