Streamwise oscillation of spanwise velocity at the wall of a channel for turbulent drag reduction
Claudio Viotti, Maurizio Quadrio, Paolo Luchini
Steady forcing at the wall of a channel flow is studied via DNS to assess its ability of yielding reductions of turbulent friction drag. The wall forcing consists of a stationary d…

Streamwise-traveling waves of spanwise wall velocity for turbulent drag reduction
M. Quadrio, P. Ricco, C. Viotti
Waves of spanwise velocity imposed at the walls of a plane turbulent channel flow are studied by Direct Numerical Simulations. We consider sinusoidal waves of spanwise velocity whi…
