We assess the efficacy of a zero-net-mass-flux blowing and suction in the form of streamwise traveling waves for controlling the onset of turbulence in a channel flow. For small amplitude actuation along the walls, we utilize perturbation analysis to determine modifications in the base flow and to examine the resulting net power balance. Sensitivity of the velocity fluctuations around this base flow is then employed as a basis for selection of traveling wave parameters. Our simulation-free… CONTINUE READING
