Aerodynamic design and Aeroelasticity analysis of Vertical Axis Wind Turbine farms

风能市场是由水平轴风力涡轮机(HAWTs)推动的，然而，垂直轴风力涡轮机(VAWTs)具有超越它们的潜力。尽管VAWTs被认为具有较低的空气动力学效率，但最近的研究表明，阵列结构的VAWTs更适合未来的风电场，因为它每平方米产生的功率明显更大。由于早期VAWTs设计中的循环应力，疲劳问题和材料失效一直是风电行业面临的一个主要问题，这阻碍了VAWTs用于风能转换的潜力的释放。计算模型方面的最新进展使人们能够深入了解风力涡轮机的空气动力和流体-结构相互作用。这些工具可以用来研究新结构和创新叶片设计的应用，以克服大多数VAWTs的疲劳问题。本研究的总体目标是加强数值和实验模型与真实条件风电场数据和创新几何结构的集成，以揭示VAWTs在单独和阵列配置中的潜在高性能。作为一个案例研究，建议的方法将被用于研究和优化一种创新的变风量风力机的空气动力学和结构完整性，该变风量风力机旨在抵御强风。诺森比亚大学的共同指导博士生将参与使用内部代码和风洞进行计算和实验建模以及风力涡轮机的优化。该行业的实验研究将用于验证数值模型的气动性能和气动弹性不稳定性预测。

The wind energy market is driven by Horizontal Axis Wind Turbines (HAWTs), however, Vertical Axis Wind Turbines (VAWTs) have the potential to outperform them. Although VAWTs are considered to have lower aerodynamic efficiencies, recent studies show that VAWTs, in array configurations, are much better suited for future wind farms by producing significantly more power per square meter.The fatigue issues and material failures, due to cyclic stresses in the earlier VAWTs designs, have been a major problem faced by the wind industry which has prevented unlocking the potential of VAWTs for wind energy conversion. Recent advances in computational modelling have enabled an in-depth understanding of the aerodynamic and fluid-structure interactions of wind turbines. These tools can be used to investigate the applications of new structures and innovative blade designs to overcome most of the fatigue issues for VAWTs.The overall aim of this research is to enhance the integration of numerical and experimental models with real-condition wind farms data and innovative geometries to reveal the potential high performance of VAWTs both individually and in array configurations. As a case study, the proposed method will be used to investigate and optimise the aerodynamics and structural integrity of an innovative VAWT which is designed to withstand strong winds.The co-supervised PhD student at Northumbria University will be involved in computational and experimental modelling and optimisation of wind turbines using an in-house code and wind tunnels. Experimental investigations in the industry will be used to validate the numerical model aerodynamic performance and aeroelastic instabilities predictions.
