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 research published in Physics of Fluids 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.
