On a posteriori error estimates for the stationary Navier-Stokes problem

Journal of Mathematical Sciences, 2008
We obtain a computable upper bound for the difference between a solution to the stationary Navier-Stokes problem and any solenoidal vector-valued function satisfying the boundary condition and possessing necessary differentiability properties. For sufficiently small velocities this estimate implies an estimate of the deviation from exact solution in ...

Existence of an Optimal Solution of a Shape Control Problem for the Stationary Navier--Stokes Equations

SIAM Journal on Control and Optimization, 1998
This paper is concerned with an optimal shape control problem for the stationary Navier-Stokes system. A two-dimensional channel flow of an incompressible, viscous fluid is examined to determine the shape of a bump on a part of the boundary that minimizes the viscous drag.

Exterior problem for the stationary Navier-Stokes equations in the Lorentz space

Mathematische Annalen, 1998
Let \(\Omega\) be an exterior domain in \(\mathbb{R}^n, n\geqslant 3\), with a smooth boundary. The stationary Navier-Stokes system is considered \[ \begin{aligned} -&\Delta v+v\cdot\nabla v+\nabla p=\text{div} F,\quad \nabla\cdot v=0 \quad \text{in \;} \Omega,\\&v=0 \quad \text{on }\partial \Omega,\quad \lim_{|x|\to\infty}v(x)=0.\end{aligned} \] Here \

Numerical resolution of optimal control problem for the in-stationary Navier–Stokes equations

Journal of Inverse and Ill-posed Problems, 2018
Abstract In this paper we present a study of optimal control problem for the unsteady Navier–Stokes equations. We discuss the existence of the solution, adopt a new numerical resolution for this problem and combine Euler explicit scheme in time and both of methods spectral and finite elements in space.

Multiscale enrichment of a finite volume element method for the stationary Navier–Stokes problem

International Journal of Computer Mathematics, 2013
In this paper, we introduce a finite volume element method for the Navier–Stokes problem. This method is based on the multiscale enrichment and uses the lowest finite element pair P1/P0. The stability and convergence of the optimal order in H1-norm for velocity and L2-norm for pressure are obtained.
