Direct numerical simulation of high aspect ratio spanwise-aligned bars
M. MacDonald, A. Ooi, R. García-Mayoral +2
We conduct minimal-channel direct numerical simulations of turbulent flow over two-dimensional rectangular bars aligned in the spanwise direction. This roughness has been often des…
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…
Turbulent flows over dense filament canopies
Akshath Sharma, Ricardo García-Mayoral
Turbulent flows over dense canopies of rigid filaments of small size are investigated for different element heights and spacings using DNS. The flow can be decomposed into the elem…
Scaling and dynamics of turbulence over sparse canopies
Akshath Sharma, Ricardo García-Mayoral
Turbulent flows within and over sparse canopies are investigated using direct numerical simulations. We focus on the effect of the canopy on the background turbulence, the part of…
Modulation of near-wall turbulence in the transitionally rough regime
Nabil Abderrahaman-Elena, Chris T. Fairhall, Ricardo García-Mayoral
Direct numerical simulations of turbulent channels with rough walls are conducted in the transitionally rough regime. The effect that roughness produces on the overlying turbulence…
