On the optimal period of spanwise wall forcing for turbulent drag reduction
Maurizio Quadrio, Federica Gattere, Marco Castelletti +1
Turbulent channel flow controlled by spanwise wall oscillations is studied using direct numerical simulations to improve how spanwise forcing reduces skin-friction drag. Harmonic w…

A simple and efficient second-order immersed-boundary method for the incompressible Navier--Stokes equations
Paolo Luchini, Davide Gatti, Alessandro Chiarini +3
An immersed-boundary method for the incompressible Navier--Stokes equations is presented. It employs discrete forcing for a sharp discrimination of the solid-fluid interface, and a…

Turbulent skin-friction drag reduction via spanwise forcing at high Reynolds number
Davide Gatti, Maurizio Quadrio, Alessandro Chiarini +2
We address the Reynolds-number dependence of the turbulent skin-friction drag reduction induced by streamwise-travelling waves of spanwise wall oscillations. The study relies on di…
