[Osama A Kandil; Ihab Adam; Tin-Chee Wong; American Institute of Aeronautics and Astronautics.; United States. National Aeronautics and Space Administration.]. Computational study of the far-field turbulent vortex-wake/exhaust plume interaction for subsonic and high speed civil transport (HSCT) airplanes is carried out. The Reynolds-averaged Navier-Stokes (NS) equations are solved using the implicit, upwind, Roe-flux-differencing, finite-volume by: 2. Vortex interactions and decay in aircraft wakes.

For aircraft smaller than the semi-span of the wake-generator, a penetration of one vortex probably covers the most hazardous region in the wake. If, however, the penetrating aircraft is on the order of the same size as the wake-generating airplane, the most hazardous location in the wake is theoretically not at the center of a by: Aircraft fuel consumption has increased by about 75% during the past 20 years and is projected to increase by to % over the next 30 years. At the present time, approximately 3% of the worldwide usage of fossil fuels is by aircraft. Ninety-nine percent of this aircraft fuel is burned by subsonic aircraft, of which a large proportion.

In this paper, computational investigations of the far-field turbulent vortex-wake/exhaust jet plume interaction for a Boeing tip vortex and a single engine, and a HSCT vortex-wake and twin engines are carried out. The Boeing is in a holding condition and the HSCT is in a cruise condition. An overlapping zonal method is used to carry out. Interaction of Wing Vortices and Plumes in Supersonic Flight.
