The dynamic course of multi-scale coherent eddystructuresbursting is researched.A periodic blowing/suction forcing, issued from a thin latitudinal slot onthe wall, is introduced to alter multi-scale ingredients of coherent eddystructure and their energy distribution in turbulent boundary layer, what ismore, to perturb and control the coherent eddy structures in order toaccomplish drag reduction of skin friction.
