1. What does vortex shedding mean?

Vortex shedding refers to the divergence, detachment, and separation of vortices; The above results are from the example sentence of Kingsoft PowerWord: 1. Numerical study of bathymetry effect on vortex shedding. Numerical study on the influence of terrain and water depth on vortex ejection.

The unified separation plane two-dimensional water flow caused by vortex induced vibration is the result of two so-called shear layers - the concentration of the region range and the existence of large velocity gradients due to the collision of bluff and road obstacles.

. From the energy in the upcoming process, the vortex shear layer continues to grow until it enters a critical stage. The two shear layers interact with each other in the form of vortices, downstream. This series of events, repeated regularly, resulted in the formation of the nominated Whirlpool Street. There is no clear requirement for the cylinder body actuator, and the interaction between these vortex flows is directly related to the frequency of the Strouhal flow velocity in the United States, as it has been named by the earliest scientist Vincenz Strouhal (1878), depending on the flow velocity and the size of the cylinder d across the flow. This dependence is reflected in the constant number of Strouhal dimensions, which is a function of the cylinder section geometry and Reynolds number R. As is well known, S=0.2 for a circular section. A description of the phenomenon of vortex shedding in a rigid fixed cylinder, where vortex streets alternate downstream cylinders. However, the assumed cylinder cannot be completely eliminated in many real vortex shedding flow sensor|rotameter flow meter

3. How does the phenomenon of wind shaking in super high-rise buildings occur? The wind induced sway of super high-rise buildings is mainly caused by wind pressure fluctuations and vortex shedding, and the building will suppress this sway through devices such as dampers. When strong winds pass around a building, alternating shedding vortices are generated on its back, creating periodic pressure differentials. This vortex shedding phenomenon is the main cause of the buildings lateral sway (perpendicular to the wind direction). At the same time, the intermittent wind itself can generate irregular thrust and suction, causing the building to vibrate in the downwind direction. To control shaking, contemporary super high-rise buildings commonly use tuned mass dampers (TMDs), such as the giant steel ball weighing 660 tons suspended inside Taipei 101 building, which counteracts building vibration
