Flow structure around a dragonfly wing model

Caption

After a sudden start, the wing's airflow comes into play. The red and blue areas show positive and negative vorticity, representing counterclockwise and clockwise flows. The curves depict streamlines. A corrugated structure near the front edge disrupts a crucial red formation, a key player in lift enhancement.
