The aim of this paper is to describe a turbulence model for the particle method Smoothed Particle Hydrodynamics (SPH). The model makes few assumptions, conserves linear and …
Abstract The Navier-Stokes-Voigt (NSV) model of viscoelastic incompressible fluid has been recently proposed as a regularization of the 3D Navier-Stokes equations for the purpose of …

Data assimilation is a methodology to estimate weather or ocean variables by combining (synchronizing) information from observational data with a numerical dynamical (forecast) …
We consider a general family of regularized Navier–Stokes and Magnetohydrodynamics (MHD) models on n-dimensional smooth compact Riemannian manifolds with or without …

Rates of convergence of solutions of various two-dimensional α-regularization models, subject to periodic boundary conditions, toward solutions of the exact Navier–Stokes …
Inviscid regularization modeling of turbulent flow is investigated. Homogeneous, isotropic, decaying turbulence is simulated at a range of filter widths. A coarse-graining of turbulent …

In this paper we prove the existence of an inertial manifold, ie, a globally invariant, exponentially attracting, finite-dimensional smooth manifold, for two different subgrid-scale α …
The present work extends Kolmogorov's micro-scales to a large family of viscoplastic fluids. The new micro-scales, combined with Gioia and Chakaborty's (2006) friction …
