Application and evaluation of the effectiveness of improving air quality by wind towers for townhouses in Da Nang

Tóm tắt

This study investigates the effectiveness of wind towers, an ancient Persian architectural feature, for natural ventilation and air quality improvement in townhouses in Da Nang, Vietnam. This study employs Computational Fluid Dynamics simulations to evaluate the performance of wind towers under various parameters, including tower shape, wind direction, height, and inlet/outlet ratios. The simulations compare different wind tower designs, such as two-sided, four-sided, and eight-sided towers, and analyze the impact of varying wind angles (0°, 45°, and 90°). The results demonstrate that wind towers can enhance indoor air velocity and ventilation flow rates, leading to improved indoor air quality and reduced pollutant levels. Notably, four-sided wind towers exhibit the most consistent performance across different wind directions. The study also finds that increasing tower height and inlet area positively affects ventilation efficiency. This study provides valuable insights for implementing wind towers as a sustainable solution for natural ventilation in urban buildings.
