Abstract
• This article presents the first comprehensive review of techniques to improve the aerodynamic performance of Archimedes Spiral Wind Turbines, focusing on their suitability for urban settings. • The findings provide critical insights for the design of more efficient wind turbines tailored for urban environments and low wind speed regions. • This study evaluates advancements in design improvements, and offers a structured overview to guide future research directions. In the global pursuit of sustainable urban energy solutions, urban centers' significant contributions to energy consumption and carbon emissions have driven cities to adopt energy efficiency policies and renewable resources. Archimedes spiral wind turbines (ASWTs) offer promising technology due to their spiral blade design, which ensures high efficiency at low to medium wind speeds, automatic wind direction alignment, and low noise emissions. This paper provides a comprehensive review and critical analysis of aerodynamic performance enhancement techniques for ASWTs, identifying key research gaps and suggesting future research directions. These include investigating the synergistic relationships of key blade dimensions such as diameter, length, and blade angle, concurrent with the development of more efficient augmentation systems, and improving advanced materials used to increase durability and reduce solidity. The analysis also compares previous methodologies and offers guidance on integrating ASWTs effectively within urban areas, contributing to cleaner and more sustainable energy solutions.
