Wing-Tip Vortices , Turbulence , and the Distribution of Emissions

  title={Wing-Tip Vortices , Turbulence , and the Distribution of Emissions},
  author={Thomas Gerz and Frank Holz{\"a}pfel},
The decay of wing-tip vortices under the in uence of turbulence in a stably stratiŽ ed atmosphere is discussed by means of large-eddy simulations. The vortices originate from a B-747 aircraft in cruise. Atmospheric turbulence and turbulence originating from the boundary layer around the aircraft are distinguished. The former is weak and anisotropic with eddy sizes in the order of the wing span, whereas the latter is wrapped around the vortices with the maximum intensity at the core diameter… CONTINUE READING
