Vortex shedding

Vortex shedding is a phenomenon that occurs when a fluid flows past a bluff (non-streamlined) body, resulting in the alternating formation and shedding of vortices from the body’s surfaces. This effect is often observed in situations where a fluid, such as air or water, flows around objects like cylinders, plates, and other shapes. When fluid flows past a bluff body, it creates regions of low pressure that lead to the formation of vortices.
