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…
Effect of a weak current on wind-generated waves in the wrinkle regime
C. Nove-Josserand, S. Perrard, A. Lozano-Duran +3
We investigate numerically the influence of a weak current on wind-generated surface deformations for wind velocity below the onset of regular waves. In that regime, the liquid sur…
Nonlinear mechanism of the self-sustaining process in the buffer and logarithmic layer of wall-bounded flows
Hyunji Jane Bae, Adrian Lozano-Duran, Beverley J. McKeon
The nonlinear mechanism in the self-sustaining process (SSP) of wall-bounded turbulence is investigated. Resolvent analysis is used to identify the principal forcing mode which pro…
Non-equilibrium three-dimensional boundary layers at moderate Reynolds numbers
Adrián Lozano-Durán, Marco Giometto, George I. Park +1
Non-equilibrium wall turbulence with mean-flow three-dimensionality is ubiquitous in geophysical and engineering flows. Under these conditions, turbulence may experience a counter-…
DNS-aided explicitly filtered LES
H. Jane Bae, Adrián Lozano-Durán
The equations for LES are formally derived by low-pass filtering the NS equations with the effect of the small scales on the larger ones captured by a SGS model. However, it is kno…
Causality of energy-containing eddies in wall turbulence
Adrián Lozano-Durán, H. Jane Bae, Miguel P. Encinar
Turbulent flows in the presence of walls may be apprehended as a collection of momentum- and energy-containing eddies (energy-eddies), whose sizes differ by many orders of magnitud…
Resolvent-based estimation of space-time flow statistics
Aaron Towne, Adrian Lozano-Duran, Xiang Yang
We develop a method to estimate space-time flow statistics from a limited set of known data. While previous work has focused on modeling spatial or temporal statistics independentl…
Characteristic scales of Townsend's wall attached eddies
Adrián Lozano-Durán, Hyunji Jane Bae
Townsend (1976) proposed a structural model for the logarithmic layer (log-layer) of wall turbulence at high Reynolds numbers, where the dominant momentum-carrying motions are orga…
