🌪️ Von Kármán Vortex Street: As fluid flows past a blunt body at critical Reynolds numbers, alternating vortices peel off from opposite sides of the obstacle in periodic oscillation. This causes periodic lift oscillations responsible for singing power cables, flutter in bridges, and aircraft turbulence.
