Vortex shedding is a fluid dynamics phenomenon that occurs when a fluid flows past a solid object, creating alternating low-pressure vortices on either side of the object. This process can lead to oscillating forces acting on the object, which can cause vibrations. Vortex shedding is commonly observed in structures like bridges and buildings, where wind interacts with their surfaces. The frequency of vortex shedding depends on factors such as the shape of the object, the flow speed of the fluid, and the fluid's properties. Engineers often consider vortex shedding when designing structures to ensure they can withstand these forces and avoid potential damage or failure.
