Natural grid stretching for DNS of wall-bounded flows
Sergio Pirozzoli, Paolo Orlandi
We propose a natural stretching function for DNS of wall-bounded flows, which blends uniform near-wall spacing with uniform resolution in terms of Kolmogorov units in the outer wal…
One-point statistics for turbulent pipe flow up to
Sergio Pirozzoli, Joshua Romero, Massimiliano Fatica +2
We study turbulent flows in a smooth straight pipe of circular cross--section up to using direct--numerical-simulation (DNS) of the Navier--Stokes equations. Th…
The three-dimensional instabilities and destruction of the Hill's vortex
Paolo Orlandi
The Hill vortex is a three-dimensional vortex structure solution of the Euler equations. For small amplitude axisymmetric disturbances on the external surface from the linear stabi…
DNS of transitional and turbulent flows in rectangular ducts
Paolo Orlandi, Sergio Pirozzoli
We carry out Direct Numerical Simulation (DNS) of flows in closed rectangular ducts with several aspect ratios. The Navier-Stokes equations are discretized through a second-order f…
Turbulent kinetic energy production and Turbulent kinetic energy production and flow structures in flows past smooth and rough walls
Paolo Orlandi
Data available in literature from direct numerical simulations of two-dimensional turbulent channels by Lee & Moser (2015), Bernardini et al. (2014), Yamamoto and Tsuji (2018) and…
Comparison between super-hydrophobic, liquid infused and rough surfaces: a DNS study
I. Arenas, E. Garcia, M. K. Fu +3
Direct Numerical Simulations of two superposed fluids in a channel with a textured surface on the lower wall have been carried out. A parametric study varying the viscosity ratio b…
