Resolvent-based predictions for turbulent flow over anisotropic permeable substrates
Andrew Chavarin, Garazi Gomez-de-Segura, Ricardo Garcia-Mayoral +1
Recent simulations indicate that streamwise-preferential porous materials have the potential to reduce drag in wall-bounded turbulent flows(Gomez-de-Segura & Garcia-Mayoral 2019).…

The smooth-wall-like behaviour of turbulence over drag-altering surfaces: a unifying virtual-origin framework
Joseph I. Ibrahim, Garazi Gómez-de-Segura, Daniel Chung +1
We conduct direct simulations of turbulent channels imposing different virtual origins for all three velocities using Robin, slip-like boundary conditions to study the effect of di…
