In the wake region, the two shear layers coming from the suction and pressure sides of the airfoil merge. The position of the merging line is computed by the inviscid flow solver. The wake merging line (or wake-cut) represents the line along which the two s hear laye rs merge, as shown in Figure 1.
The flow downstream of a body immersed in a stream, or the flow behind a body propagating through a fluid otherwise at rest. Wakes are narrow elongated regions aligned with flow direction and filled with large and small eddies, which are vortexlike motions of a fluid running contrary to the main current.

Separation occurs due to an adverse pressure gradient encountered as the flow expands, causing an extended region of separated flow. The part of the flow that separates the recirculating flow and the flow through the central region of the duct is called the dividing streamline.
The wake is the region of disturbed flow (often turbulent) downstream of a solid body moving through a fluid, caused by the flow of the fluid around the body.
Wake is basically any disturbed fluid behind an object. A vortex is a rotating (spinning)flow. A wake can contain (be) a vortex. A wake results when the flow separates from an object.
Donald Coles ing to this interpretation, the law of the wake is to be viewed as a manifestation of a large-scale mixing process similar to flow in a wake, in that it is constrained primarily by inertia rather than by viscosity.
Firstly, dirty air is just an alternative term for aerodynamic wake – this is the region of disturbed air generated as a vehicle passes through the stationary air itself.
The near wake is the region from the turbine to approximately one or two rotor diameters downstream, where the turbine geometry directly affects the flow, leading to the presence of distinct tip vortices. Tip and root vortices lead to sharp gradients in the velocity and peaks in the turbulence intensity.
Flow separation occurs when fluid detaches from a surface due to adverse pressure gradients. This phenomenon leads to wake formation, increased drag, and reduced lift.
