WebIn fluid dynamics, a wake may either be: the region of recirculating flow immediately behind a moving or stationary blunt body, caused by viscosity, which may be accompanied by flow separation and turbulence, or WebMar 19, 2024 at 23:06. 4. Whether or not a duplicate question, the answer to this Q is contained in that answer. Essentially, the generation of lift "forces" the air downward. This downward momentum is what causes the vorticies (i.e. wake turbulence). The vortices sink with the downward deflected air that caused them.

Web17. How does the wake turbulence vortex circulate around each wingtip? A. Inward, upward, and around each tip. B. Inward, upward, and counterclockwise. C. Outward, upward, and around each tip. The vortex circulation is outward, upward, and around the wing tips when viewed from either ahead or behind the aircraft. 18. WebThe greater of the weight of the aircraft the more intense will be the wake turbulence particularly when affected aircraft has a shorter wing span than that of the general aircraft.

WebNov 21, 2024 · Notice how the air becomes more turbulent behind the car and vortices start to occur in the wake. Bottom: Form drag: A box-shaped vehicle (such as a large truck) makes no attempt to divert air around itself. As soon as the air smacks into it, it starts to become turbulent.
