Alternative physics to understand wall turbulence: Navier-Stokes equations with modified linear dynamics
Adrán Lozano-Durán, Marios-Andreas Nikolaidis, Navid C. Constantinou +1
Despite the nonlinear nature of wall turbulence, there is evidence that the energy-injection mechanisms sustaining wall turbulence can be ascribed to linear processes. The differen…
The Nusselt numbers of horizontal convection
Cesar. B. Rocha, Navid C. Constantinou, Stefan G. Llewellyn Smith +1
We consider the problem of horizontal convection in which non-uniform buoyancy, , is imposed on the top surface of a container and all other surfaces are insulating…
Wall turbulence without modal instability of the streaks
Adrián Lozano-Durán, Marios-Andreas Nikolaidis, Navid C. Constantinou +1
Despite the nonlinear nature of wall turbulence, there is evidence that the mechanism underlying the energy transfer from the mean flow to the turbulent fluctuations can be ascribe…
Eddy saturation of the Southern Ocean: a baroclinic versus barotropic perspective
Navid C. Constantinou, Andrew McC. Hogg
"Eddy saturation" is the regime in which the total time-mean volume transport of an oceanic current is relatively insensitive to the wind stress forcing and is often invoked as a d…
Kinetic energy of eddy-like features from sea surface altimetry
Josué Martínez-Moreno, Andrew McC. Hogg, Andrew E. Kiss +2
The mesoscale eddy field plays a key role in the mixing and transport of physical and biological properties and redistribute energy budgets in the ocean. Eddy kinetic energy is com…
Wall turbulence with constrained energy extraction from mean flow
Adrián Lozano-Durán, Michael Karp, Navid. C. Constantinou
We study the mechanism of energy injection from the mean flow to the fluctuating velocity necessary to maintain wall turbulence. This process is believed to be correctly represente…
Magnetic eddy viscosity of mean shear flows in two-dimensional magnetohydrodynamics
Jeffrey B. Parker, Navid C. Constantinou
Magnetic induction in magnetohydrodynamic fluids at magnetic Reynolds number (Rm) less than~1 has long been known to cause magnetic drag. Here, we show that when $\mathrm{Rm} \gg 1…
