WebWake turbulence is a disturbance in the atmosphere that forms behind an aircraft as it passes through the air. It includes a variety of elements, the most significant of which are wingtip vortices and jetwash. Jetwash refers to the rapidly moving gases expelled from a jet engine; it is extremely turbulent but of short duration. WebApr 20, 2006 · The airfoil (NACA 0012 basic thickness form) was located in a wind tunnel, and the wake structure was measured using hot-wire sensors. The measurements of mean-velocity, turbulence intensity and Reynolds-stress components across the wake at several distances downstream show the complex nature of the near wake and its asymmetrical …
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.
