An optimal order interior penalty discontinuous Galerkin discretization of the compressible Navier-Stokes equations [PDF]

, 2008
In this article we propose a new symmetric version of the interior penalty discontinuous Galerkin finite element method for the numerical approximation of the compressible Navier-Stokes equations.

Rheology of compressible and density-variable Newtonian flows: non-Stokes hypothesis and ‘volume diffusion’

Journal of Physics Communications
Stokes’ hypothesis allows for the frequent neglect of the bulk viscosity term related to fluid dilation effects on the viscous stress tensor in Newtonian flows.

The Asymptotic Stability of the Generalized 3D Navier-Stokes Equations

Journal of Applied Mathematics, 2013
We study the stability issue of the generalized 3D Navier-Stokes equations. It is shown that if the weak solution u of the Navier-Stokes equations lies in the regular class ∇u∈Lp(0,∞;Bq,∞0(ℝ3)), (2α/p)+(3/q)=2α ...

Reproductive solutions for the g-Navier-Stokes and g-Kelvin-Voight equations

Electronic Journal of Differential Equations, 2016
This article presents the existence of reproductive solutions of g-Navier-Stokes and g-Kelvin-Voight equations. In this way, for weak solutions, we reach basically the same result as for classic Navier-Stokes equations.

Finite Element Modelling of the Hydrodynamic Environment of a Small ROV [PDF]

Modeling, Identification and Control, 1993
This paper addresses a practical problem, namely, modeling the hydrodynamic environment of a small ROV. This has become the problem of solving time-dependent incompressible Navier-Stokes equations with moving boundaries and a new method is developed to ...

Efficient Algorithms for Solution of the Adjoint Compressible Navier-Stokes Equations with Applications [PDF]

, 2006
The complete discrete adjoint equations for an unstructured finite volume compressible Navier-Stokes solver are discussed with respect to the memory and time efficient evaluation of their residuals, and their solution.

EQUATION OF CONTINUITY IN THE CYLINDRICAL COORDINATES SYSTEM

Известия высших учебных заведений: Нефть и газ, 2016
Sophisticated viscous compressible heat-conducting gases arising during heating the vertical field, have a pronounced axial symmetry. Therefore, for the numerical solution of the full Navier - Stokes equations to describe such gas flows is advisable to ...
