Linearised Navier-Stokes equations and near-wall streaks in turbulent flow subject to drag reduction by wall oscillations
Spanwise wall-oscillation is a promising drag reduction technique in turbulent flows. A major factor in drag reduction is the effect of the oscillations on the boundary layer coherent structures, and particularly the weakening of the near-wall streaks. This thesis studies the streaks in various wall...
