Handling geometric singularities efficiently with the immersed-boundary method: application to riblets
Stefano Cipelli, Alessandro Chiarini, Maurizio Quadrio +2
We present an enhancement of classical immersed boundary methods for the direct numerical simulation of the incompressible Navier-Stokes equations, designed to efficiently cope wit…
Energy transfer and scale organisation in dense canopy turbulence
Riccardo Bertoncello, Alessandro Chiarini, Giulio Foggi Rota +2
This study identifies the scale-dependent processes that sustain turbulence in dense submerged canopy flows. Using a scale-resolved energy budget, we determine where in space and a…
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…
The aerodynamic performance of a transonic airfoil with spanwise forcing
Niccolò Berizzi, Davide Gatti, Giulio Soldati +2
Spanwise wall forcing in the form of streamwise-travelling waves is applied to the suction side of a transonic airfoil with a shock wave to reduce aerodynamic drag. The study, cond…
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…
Spatial discretization effects in spanwise forcing for turbulent drag reduction
Emanuele Gallorini, Maurizio Quadrio
Wall-based spanwise forcing has been experimentally used with success by Auteri et al. (Phys. Fluids vol. 22, 2010, 115103) to obtain large reductions of turbulent skin-friction dr…
