摘要:... Various flow-control devices are studied by Direct Numerical Simulation, which is free of modeling and provides the full details of the pressure field. The Reynolds number is far lower than in the real flow, but this limitation of DNS is tolerable, because the focus is on ...

摘要:Abstract(#br)A well-resolved large eddy simulation (LES) of a large-eddy break-up (LEBU) device in a spatially evolving turbulent boundary layer is performed with, Reynolds number, based on free-stream velocity and momentum-loss thickness, of R e θ ≈ 4300. The implementation...

摘要:The effects of implementing a large-eddy break-up device (LEBU) in a turbulent boundary layer on the interaction with the boundary layer is investigated with particular emphasis on the turbulent/non-turbulent interface (TNTI). The simulation data is taken from a recent well-r...

摘要:A well-resolved large eddy simulation (LES) of alarge-eddy break-up (LEBU) device in a spatially evolvingturbulent boundary layer up to Reθ ~ 4300 is performed.The LEBU is a flat plate that is implemented via an immersedboundary method. Initial flow visualizations ...

摘要:This chapter discusses direct numerical simulation of large-eddy-break-up devices in a boundary layer. Turbulent boundary layers create aerodynamic noise inside all vehicles, and especially inside jetliners. The chapter modifies the turbulence, not to reduce skin friction, bu...
