چکیده

We consider the Stokes problem with slip type boundary conditions in the half-space R+, with n > 2. The weighted Sobolev spaces yield the functional framework. We study generalized and strong solutions and then the case with very low regularity of data on the boundary. We apply the method of decomposition introduced in our previous work (see [7]), where it is necessary to solve particular problems for harmonic and biharmonic operators with very weak data. We also envisage a wide class of behaviour at in nity for data and solutions.

Notes on Navier - Stokes - Fourier system

These Lecture Notes are devoted to some aspects of the theory of the Navier-Stokes-Fourier system. We shall discuss 1) existence of weak solutions, 2) existence of suitable weak solutions and relative entropies, 3) weak strong uniqueness property in the class of weak solutions. For physical reasons, we shall limit ourselves to the three dimensional physical space, and for the sake of simplicity...

On boundary regularity of the Navier-Stokes equations

We study boundary regularity of weak solutions of the Navier-Stokes equations in the half-space in dimension . We prove that a weak solution which is locally in the class with near boundary is Hölder continuous up to the boundary. Our main tool is a point-wise estimate for the fundamental solution of the Stokes system, which is of independent interest.

Inviscid limits for the Navier-Stokes equations with Navier friction boundary conditions

We consider the Navier-Stokes equations with Navier friction boundary conditions and prove two results. First, in the case of a bounded domain we prove that weak Leray solutions converge (locally in time in dimension ≥ 3 and globally in time in dimension 2) as the viscosity goes to 0 to a strong solution of the Euler equations provided that the initial data converges in L2 to a sufficiently smo...

A comparative study between two numerical solutions of the Navier-Stokes equations

The present study aimed to investigate two numerical solutions of the Navier-Stokes equations. For this purpose, the mentioned flow equations were written in two different formulations, namely (i) velocity-pressure and (ii) vorticity-stream function formulations. Solution algorithms and boundary conditions were presented for both formulations and the efficiency of each formulation was investiga...

On the Nonhomogeneous Navier-Stokes System with Navier Friction Boundary Conditions

In this talk we address the issue of existence of weak solutions for the non-homogeneous Navier-Stokes system with Navier friction boundary conditions allowing the presence of vacuum zones and assuming rough conditions on the data. We also study the convergence, as the viscosity goes to zero, of weak solutions for the non-homogeneous Navier-Stokes system with Navier friction boundary conditions...
