Testo completoMany industrial applications involve flows periodic in time. Flutter prediction or turbomachinery flows are some examples. Such flows are not simulated with enough efficiency when using classical unsteady techniques as a transient regime must be by-passed. New techniques, dedicated to time-periodic flows and based on Fourier analysis, have been developed recently. These methods, called harmonic balance, cast a time-periodic flow computation in several coupled steady computations, corresponding to a uniform sampling of the period. Their efficiency allow to get a precision good enough for engineering but much faster than classical nonlinear timemarching algorithms. The present study aims at imlementing one of these, the Time Spectral Method, in the ONERA solveur elsA. It is extended to an arbitrary lagrangian/eulerian formulation to take into mesh deformation for aeroelasticity applications. New implicit algorithms are developped to improve robustness. The TSM is successfully validated on external aerodynamic applications. Turbomachinery flows necessitate complex space and time interpolations ro reduce the computational domain to a single blade passage per row regardless of its geometry. Some applications in rotor/stator interactions and aeroelasticity are presented

Testo completoThis work concerns the direct numerical simulation of a new instability phenomenon occuring in confined rotating gas flows. It confirms the analytical results of J. F. Scott and J. P. Racz (2001) and the experimental work of L. Graftieaux (2003). A parametric resonance mechanism leads to conditional growth of inertial mode pair coupled by harmonic oscillations of a piston. A numerical code was developed under the assumption of axisymmetry of the flow, based on a galerkin-type spectral method. Special treatment of the velocity singularities in the cylinder corners is based on the substraction of an analytical lly specified flow the mimics the corner singularities. The results allow complete characterization of inertial mode pairs coupled by resonance, with particular attention focused on the primary axisymmetric mode studied experimentally. A marginal stability diagram and an exploration of the nonlinear regime were performed

Testo completoNumerical resolution of partial differential equations can be made reliable and efficient through the use of adaptive numerical methods. We present here the work we have done for the design, the implementation and the validation of such a method within an industrial software platform with applications in thermal-hydraulics. From the geometric point of view, this method can deal both with mesh refinement and mesh coarsening, while ensuring the quality of the mesh cells. Numerically, we use the mortar elements formalism in order to extend the Finite Volumes-Elements method implemented in the Trio-U platform and to deal with the non-conforming meshes arising from the adaptation procedure. Finally, we present an implementation of this method using concepts from domain decomposition methods for ensuring its efficiency while running in a parallel execution context

Testo completoDespite tremendous improvements in graphics hardware performance aswell as key algorithmic advancements since the beginning of the years 2000, some natural phenomena remain extremely costly to simulate. For instance, several tracks have been proposed to improve the performance of fluid simulations, that are animated by solving partial differential equations (PDE), more specifically the highlynon-linear Navier-Stokes equations. In this thesis, we first explore the use of deep learning to create a reduced space in which a solver can operate with lower costs, while still out putting high-quality solutions. We propose a model that enables the simulation of turbulent flows at a resolution four times higher than that of the given input in each dimension, with improved runtime performance compared to a high-resolution solver. Secondly, we use the contributions on intrinsic operators for simulating fluids on 3D surfaces with reduced costs. We focus on the smoothed-particle hydrodynamics (SPH) model that we adapt to 3D surfaces, by gathering the particles' neighborhoods thanks to shortest-path geodesics, and by displacing such particles in an intrinsic manner on the surface. All of this is straightforward to implement on the GPU, enablingthe simulation of tens of thousands of particles on various triangle meshes at interactive speed
