    is the freestream Mach number, and ,, are the surface-normal vector components. The unknown variable is the perturbation potential ϕ ( x , y , z ) {\displaystyle \phi (x,y,z)} , and the total velocity is given by its gradient plus the freestream velocity V ∞ {\displaystyle V_{\infty }} which is assumed here to be along x {\displaystyle x} .

    The freestream is the air far upstream of an aerodynamic body, that is, before the body has a chance to deflect, slow down or compress the air. Freestream conditions are usually denoted with a ∞ {\displaystyle \infty } symbol, e.g. V ∞ {\displaystyle V_{\infty }} , meaning the freestream velocity.

  5. Relative wind - Wikipedia

    This vector is the relative wind or the free stream velocity vector. [1] The angle between the chord line of an airfoil and the relative wind defines the angle of attack. The relative wind is of great importance to pilots because exceeding the critical angle of attack will result in a stall, regardless of airspeed.
