Simulations of spatially developing turbulent boundary layers with localized application of three different control techniques aimed at reduction of skin friction drag. Considered control techniques are uniform blowing, body-force damping of wall-normal velocity component and opposition control.

Key Data

  • pseudo-spectral solver SIMSON External Link
  • streamwise and spanwise periodicity of simulation domain
  • weak random forcing for turbulence tripping
  • Grid size Nx×Ny×Nz=3072×301×256
  • Domain size Lx×Ly×Lz=3000×120×100 (based on initial displacement thickness)
  • uncontrolled flow: Reθ=400-2500, Reτ=170-850
  • three control types: uniform blowing with 0.5%U∞, damping of wall-normal velocity component by imposition of body force and opposition control scheme
  • control region location: x=186-386
