The airflow from an indoor badminton court's HVAC system and cross ventilation can affect the path of a birdie and have a significant role in play, but new research proposes that different roof configurations could help mitigate wind drift. The authors recommend that important badminton games be played on courts with a barrel roof and a ventilation opening. The team modeled the airflow in a barrel roof stadium with different ventilation opening directions and tested this against a simulation of a flat roof to understand the roof effects.
