Freestream air velocity

WebA uniform flow consists of a velocity field where V~ = uˆı+ v ˆ is a constant. In 2-D, this velocity field is specified either by the freestream velocity components u ∞, v ∞, or by the freestream speed V ∞ and flow angle α. u = u ∞ = V ∞ cosα v = v ∞ = V ∞ sinα Note also that V2 ∞ = u2 ∞ +v2 ∞ WebMay 2, 2024 · At the outer edge of this viscous region, where the flow is no longer affected or slowed by the surface generated friction, the velocity is called the “freestream” value. …
