This thesis deals with the steady incompressible Navier-Stokes equations, more precisely with the asymptotic behavior of its solutions when |x| → ∞. We consider several types of unbounded domains and we assume that the velocity vanishes at infinity. We first look at the three dimensional case, for which we know that if the forcing term decays fast enough at infinity, the asymptotic behavior of the solutions is given by the Landau solutions that are homogeneous of degree -1. We generalize this result to small forcing terms whose asymptotic behavior at infinity is homogeneous of degree -3. To obtain solutions with an asymptotic behavior at infinity homogeneous of degree -1 we find a necessary and sufficient condition on the forcing : the homogeneous part of the forcing term must have zero mean over the unit sphere. Finally, we generalize this result to the case of an exterior domain. In the case of a half space, we prove that if the forcing term decays sufficiently fast at infinity, then we obtain solutions that decay as 1/|x|2 at infinity and we find an explicit formula for the dominant term in the expansion at infinity of the solution. We can also prove the same type of result as in the full space with forcing terms decaying like 1/|x|3 but the condition of zero mean over the sphere is not required any more. The case of the dimension two is much more difficult. We study first homogeneous solutions and find a family indexed on two real parameters. Imposing the restriction of having zero flux through the unit circle, we get a family of solutions with only one parameter. Finally we deal with non homogeneous solutions, but to do this we need to assume some symmetry conditions on the data. If the forcing term is small and decays sufficiently fast at infinity, we find solutions that decay like 1/|x|3 at infinity and we also obtain an explicit formula for the main term in their asymptotic expansion. We generalize this result to the case of an exterior domain and we also obtain, again under symmetry assumptions, an analogous result to the three dimensional case for forcing terms that decay like 1/|x|3 at infinity
Taymans, Claire. "Solving Incompressible Navier-Stokes Equations on Octree grids : towards Application to Wind Turbine Blade Modelling." Thesis, Bordeaux, 2018. http://www.theses.fr/2018BORD0157/document.
The subject of the thesis is the development of a numerical tool that allows to model the flow around wind blades. We are interested in the solving of incompressible Navier-Stokes equations on octree grids, where the smallest scales close to the wall have been modelled by the use of the so-called Wall Functions. An automatic Adaptive Mesh Refinement (AMR) process has been developed in order to refine the mesh in the areas where the vorticity is higher. The structural model of a real wind blade has also been implemented and coupled with the fluid model. Indeed, an application of the numerical tool is the study of the effects of wind gusts on blades. An experimental work has been conducted with an in-service wind turbine with the measurement of wind speed upstream. This data will allow to calibrate and validate the numerical models developed in the thesis

This work concerns wavelet numerical methods for the simulation of incompressible turbulent flow. The main objective of this work is to take into account physical boundary conditions in the resolution of Navier-Stokes equations on wavelet basis. Unlike previous work where the vorticity field was decomposed in term of classical wavelet bases, the point of view adopted here is to compute the velocity field of the flow in its divergence-free wavelet series. We are then in the context of velocity-pressure formulation of the incompressible Navier-Stokes equations, for which the boundary conditions are written explicitly on the velocity field, which differs from the velocity-vorticity formulation. The principle of the method implemented is to incorporate directly the boundary conditions on the wavelet basis. This work extends the work of the thesis of E. Deriaz realized in the periodic case. The first part of this work highlights the definition and the construction of new divergence-free and curl-free wavelet bases on [0,1]n, which can take into account boundary conditions, from original works of P. G. Lemarie-Rieusset, K. Urban, E. Deriaz and V. Perrier. In the second part, efficient numerical methods using these new wavelets are proposed to solve various classical problem: heat equation, Stokes problem and Helmholtz-Hodge decomposition in the non-periodic case. The existence of fast algorithms makes the associated methods more competitive. The last part is devoted to the definition of two new numerical schemes for the resolution of the incompressible Navier-Stokes equations into wavelets, using the above ingredients. Numerical experiments conducted for the simulation of driven cavity flow in two dimensions or the issue of reconnection of vortex tubes in three dimensions show the strong potential of the developed algorithms

The nuclear reactor core is a highly heterogeneous medium crowded with numerous solid obstacles and macroscopic thermohydraulic phenomena are directly affected by localized phenomena. However, modern computing resources are not powerful enough to carry out direct numerical simulations of the full core with the desired accuracy. This thesis is devoted to the development of Multiscale Finite Element Methods (MsFEMs) to simulate incompressible flows in heterogeneous media with reasonable computational costs. Navier-Stokes equations are approximated on the coarse mesh by a stabilized Galerkin method, where basis functions are solutions of local problems on fine meshes by taking precisely local geometries into account. Local problems are defined by Stokes or Oseen equations with appropriate boundary conditions and source terms. We propose several methods to improve the accuracy of MsFEMs, by enriching the approximation space of basis functions. In particular, we propose high-order MsFEMs where boundary conditions and source terms are chosen in spaces of polynomials whose degrees can vary. Numerical simulations show that high-order MsFEMs improve significantly the accuracy of the solution. A multiscale simulation chain is constructed to simulate successfully flows in two- and three-dimensional heterogeneous media
Mitra, Sourav. "Analysis and control of some fluid models with variable density." Thesis, Toulouse 3, 2018. http://www.theses.fr/2018TOU30162/document.
In this thesis we study mathematical models concerning some fluid flow problems with variable density. The first chapter is a summary of the entire thesis and focuses on the results obtained, novelty and comparison with the existing literature. In the second chapter we study the local stabilization of the non-homogeneous Navier-Stokes equations in a 2d channel around Poiseuille flow. We design a feedback control of the velocity which acts on the inflow boundary of the domain such that both the fluid velocity and density are stabilized around Poiseuille flow provided the initial density is given by a constant added with a perturbation, such that the perturbation is supported away from the lateral boundary of the channel. In the third chapter we prove the local in time existence of strong solutions for a system coupling the compressible Navier-Stokes equations with an elastic structure located at the boundary of the fluid domain. In the fourth chapter our objective is to study the null controllability of a linearized compressible fluid structure interaction problem in a 2d channel where the structure is elastic and located at the fluid boundary. In this chapter we establish an observability inequality for the linearized fluid structure interaction problem under consideration which is the first step towards the direction of proving the null controllability of the system
