Advancements in Wind Energy: Exploring the Potential of Diffuser Augmented Wind Turbines (DAWTs)
Year: 2025
Type: article
Abstract: This paper explores recent advancements in wind turbine technology, focusing on Diffuser Augmented Wind Turbines (DAWTs). It provides a thorough review of the various research studies related to wind turbines equipped with diffusers, highlighting both numerical simulations and experimental data. The review categorizes the literature into two main areas: studies on the performance and operation of wind turbines with diffuser augmentation and comparative analyses of different types of DAWTs. The key parameters of diffuser design, such as length, open-angle, and the effect of flanged versus un-flanged configurations, are examined to determine their impact on power output and efficiency. The findings reveal that DAWTs significantly enhance wind turbine performance by increasing wind velocity through the rotor plane, surpassing the traditional Betz limit. This advancement results in higher power outputs, reduced noise, and improved tolerance to yaw angle variations. Despite these advantages, the commercialization of DAWTs faces challenges, including high initial costs, maintenance issues, and the complexity of integrating aerodynamic, material, and control system innovations. The paper concludes that while DAWTs offer promising improvements in wind energy efficiency, overcoming these challenges through innovative design and manufacturing approaches is crucial for their broader adoption in sustainable energy generation.
