Abstract

A method for large-eddy simulation of aircraft wake vortices embedded in planetary boundary turbulence is outlined. A nested grid scheme and three-dimensional initial and boundary conditions are described and demonstrated. The nested grid scheme allows multiple one-way or two-way simulations using mass-conservative interpolation and averaging schemes along with radiative boundary conditions which lets unwanted wave energy pass out of the finer mesh domains. The three-dimensional wake vortex initial and boundary conditions enforce fully-developed wake vortices on the upstream boundary but permit the vortices within the domain to develop spatially and temporally. Future work will entail combining the two schemes for simulations of wake vortices embedded within the convective planetary boundary layer.
