Computational analysis of wind drift and ventilation comfort in a different isolated barrel roof configuration for badminton stadium.

This article focuses on the influence of barrel roof configurations and cross-ventilation opening directions on wind drift and ventilation comfort in indoor badminton stadiums. Using computational fluid dynamics (CFD) simulations validated against wind tunnel data, the study compares three barrel roof heights with longitudinal and lateral ventilation openings to a flat roof model. Results indicate that a barrel roof with a longitudinal ventilation opening at a height 5% less than the standard roof height (95 mm) reduces wind drift near the ground by 42% while maintaining efficient ventilation, outperforming other configurations. The study highlights the trade-off between minimizing wind drift, which affects shuttlecock trajectory, and ensuring adequate ventilation, recommending specific barrel roof designs for improved indoor badminton stadium performance.
