Abstract
Computations were performed to investigate the 3D, shock-wave/boundary-layer interactions on a flat plate with bleed through four staggered rows of circular holes that discharge into a plenum. The focus is to extract understanding that can be used to construct a bleed boundary condition for CFD computations of inlet-bleed systems without the need to resolve the flow through each bleed hole in the spirit of 'turbulent wall functions'. A preliminary framework for such a boundmy condition and the ingredients necessary for it to be useful are outlined. The computations reported in this study are based on the ensemble-averaged, 'full compressible' Navier-Stokes (N-S) equations closed by the Baldwin-Lomax algebraic turbulence model. Solutions to the ensemble-averaged N-S equations were obtained by a diagonalized ADI scheme utilizing central differencing with a blended second- and fourth-order dissipation on a Chimera overlapping grid.
