Traditional wind towers, as passive cooling building components, represent an outstanding achievement of human wisdom in adapting to extremely hot and arid climates. Taking traditional wind towers in typical regions, including Iran, Iraq, Egypt, Sistan and Hyderabad, as research objects, this paper compares and summarizes the regional adaptation strategies of traditional wind towers in hot-dry climate zones and monsoon climate zones, and further generalizes their locally-adapted, climate-responsive design concepts in terms of morphological combination, material selection and air distribution.On this basis, computational fluid dynamics (CFD) numerical simulations under different design parameters are adopted to systematically analyze the internal air distribution characteristics and ventilation mechanisms of traditional wind towers from two dimensions: site wind direction and tower height. The results show that the surrounding thermal-wind environment and structural morphology jointly determine the overall ventilation performance of wind towers. Orthogonal internal partitions achieve superior ventilation efficiency and stability under multi-directional wind conditions, and reasonable air inlet height and top morphology can significantly improve wind-catching capacity. |
