A review of the recent development of innovative wind turbines: Concepts and aerodynamic analyses

Amid the escalating global demand for renewable energy sources, wind energy has emerged as a pivotal player, positioning itself as the primary energy solution for many countries and regions. The evolution of wind turbine technology has not only elevated the cost-effectiveness and efficiency of wind power but has also been instrumental in diversifying energy portfolios. From innovative blade designs to cutting-edge data analytics and extending its reach from land-based to deep-sea deployments, the breakthroughs in modern wind turbines are charting new horizons for sustainable development. This paper summarizes the conceptual design and most recent development of three types of novel wind turbines: two-bladed wind turbines, dual-rotor wind turbines, and vertical-axis wind turbines. Additionally, it delves into the aerodynamic research methods behind these three novel wind turbines. Our objective is to give readers a comprehensive insight into these research techniques.
