Global attractors and determining modes for the 3D Navier-Stokes-Voight equations

VK Kalantarov, ES Titi - Chinese Annals of Mathematics, Series B, 2009 - Springer
The authors investigate the long-term dynamics of the three-dimensional Navier-Stokes-
Voight model of viscoelastic incompressible fluid. Specifically, upper bounds for the number …

[HTML][HTML] Onsager's conjecture for subgrid scale α-models of turbulence

DW Boutros, ES Titi - Physica D: Nonlinear Phenomena, 2023 - Elsevier
The first half of Onsager's conjecture states that the Euler equations of an ideal
incompressible fluid conserve energy if u (⋅, t)∈ C 0, θ (T 3) with θ> 1 3. In this paper, we …

We prove higher-order and a Gevrey class (spatial analytic) regularity of solutions to the
Euler-Voigt inviscid $\alpha $-regularization of the three-dimensional Euler equations of …

On unique ergodicity in nonlinear stochastic partial differential equations

We illustrate how the notion of asymptotic coupling provides a flexible and intuitive
framework for proving the uniqueness of invariant measures for a variety of stochastic partial …

Pullback attractors for three-dimensional non-autonomous Navier–Stokes–Voigt equations

J García-Luengo, P Marín-Rubio, J Real - Nonlinearity, 2012 - iopscience.iop.org
In this paper, we consider a non-autonomous Navier–Stokes–Voigt model, with which a
continuous process can be associated. We study the existence and relationship between …

WJ Layton, LG Rebholz - International Journal of Computational …, 2013 - Taylor & Francis
We study analytically and numerically the relaxation time of flow evolution governed by the
Navier-Stokes-Voigt (NSV) model. We first show that for the Taylor–Green vortex decay …
