2.1.1 Flow separation and vortex-shedding mechanism
The process of flow separation from the surface of a cylinder and its consequent vortex-shedding and formation of vortex street were explained through Figure 2.1.
Moreover, in the supercritical range, the fluctuating drag and lift coefficients are very low, which is mainly due to flow separation at large angular positions that results in weaker vortices [7].
It was explained that the flow separation in such bluff bodies results in vortices which shed alternatively from two sides of the cylinders and create variable pressure fields around these cylinders.
