Key Details
Vortex shedding, streaks and recirculation form the cylinder's wake
Recirculation changes link to vortex radial position and streak strength
Vortex azimuthal position switches between circular and flapping patterns
Rotational shear happens when the vortex path is circular
Information flows from low to high wavenumbers, starting with recirculation

Wake structures behind a streamlined cylinder
This paper investigates the complex wake behind a cylinder aligned with airflow. It finds relationships between key structures like vortex shedding, streaks, and recirculation using modal analysis of velocity data. The paper clarifies how these phenomena interact, with recirculation changes affecting vortex position and streak strength.
