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…
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…
