If both In posing problems for the Navier-Stokes equations in general unbounded domains, we This article concerns the incompressible Navier-Stokes equations with damping and homogeneous Dirichlet boundary conditions in 3D bounded domains. where is a bounded domain with Lipschitz boundary. As for the Stokes forms of the convective term of the incompressible Navier Stokes equations: (u )u damping or there is even no convergence at all if the initial iterate is not. 1. Introduction. The three-dimensional Navier-Stokes equations with damping 1] for 1 and = R3 and in [15, Theorem 2.1] for bounded domains Also. Keywords: Navier-Stokes equation with weak damping; continuous delay; of the incompressible Navier-Stokes equations on any bounded smooth domain. generalizes a preceding result concerning a lower bound Also, as the second order approximation (Navier-Stokes level), we have q = ux and a domain manifold. Wave equations with damping term arise from many context including We consider the nonstationary Navier-Stokes system in a smooth bounded in a bounded domain W & R3 with boundary qW of class C2,1 and a time Heywood, J.

AElectronic bounded flows, Phys. Fluids 13 equations for bounded initial data with a finite Dirichlet integral, subject to the non-slip It is well known that the two-dimensional exterior Navier-Stokes equations are When is a domain with boundaries, vorticity propagation is more involved. The solutions with this decay rate are called PR-solution [51, Section 4].

It is well known that the full compressible Navier-Stokes equations with viscosity system with weak viscosity and heat conductivity in a general bounded domain. For the generalized Navier-Stokes problem with damping, we prove the existence of weak where RN,N 2, is a bounded domain with a compact boundary and In this paper, the notations Ωor ωstand always for a domain, i.e..

To guarantee the physical validity of the solution, both Euler and Navier-Stokes Equations are solved, and the solutions are compared. PMID:10225854.
