Wake flow evolution behind a circular cylinder with two perpendicular slits at various angles of attack

A wind tunnel experiment was performed to study the wake vortex dynamic behind a circular cylinder with two perpendicular slits (TPS) using time-resolved particle image velocimetry. The experimental studies were conducted at a Reynolds number of 1767 based on the incoming airflow and the diameter of...
