When a fluid flow past a cylindrical body, flow separation
occurs in which vortices are shed from the top and bottom of the
body alternately as shown in Figure 3 where A and C represent the
vortices from top side while B represents the vortices from the
bottom side of the body. The frequency of the vortex shedding, 𝑓𝑣
is a function of the incoming velocity 𝑢, cylinder diameter 𝐷,
density 𝜌 and viscosity 𝜇 of the fluid. Find the nondimensional
relationship of 𝑓𝑣 and what is the significance of it.
