Full textNumerical simulations in fluid mechanics require tremendous computational power ; GPU computing is one of the newest approaches to accelerate such simulations. On one hand, this thesis studies the case of fluid mechanics algorithms on structured meshes. The mesh structuration naturally brings well suited memory arrangements and allows to reach guidelines when using GPUs for numerical simulations. On the other hand, we examine the case of fluid mechanics on unstructured meshes with the help of three different algorithmic strategies. The first of these technique is a reorganisation to produce consecutive data accesses, but at the cost of expensive data copies, both in time and in memory. The second technique, a cell partitioning approach, is developed and allows to extensively use modern GPUs’ cache memories. The third technique consists on a generic refinement. The initial mesh is made of coarse elements refined in the exact same way in order to produce consecutive memory accesses. This approach brings significant performance improvements for fluid mechanics simulations on unstructured meshes

Full textFictitious domain methods allow to simulate flows around complex and/or moving bodies with simple meshes. The object is "immersed" in a domain that contains fluid and solid volumes. The penalization method, which consists in adding a term in the momentum balance equation, in order to impose the solid velocity, is studied in a first part. Thanks to asymptotic expansions, the order of the error induced by this method is computed for moving bodies. This approach is then coupled with a Vector Penalty Projection scheme that permits to impose the incompressibility constraint. The convergence of the penalized scheme towards the Navier-Stokes equations is established. In a second part, an original approach, able to treat multiphase flowsis presented: the Time and Space Dependent Porosity method. The key idea is to consider the solid as a medium without mass. The discretization of the mass balance equation is modified,so that the total volume occupied by all fluid phases and the solid is equal to the total volume.This method is numerically validated on a set of various test cases including incompressible or compressible single phase flows and two-phase flows

Full textIn order to interpret recorded temperatures in petroleum wellbores, and thus to better characterize reservoirs, we develop a direct model, coupling the wellbore and the reservoir at both dynamic and thermal levels. To reach this goal, we couple a reservoir model, notably including viscous dissipation and compressibility effect, with a new pseudo 1D model. The original aspect of the latter model is to derive a conform approximation from a 2D model and by this way, to take into account the privileged direction of the flow, as well as the particular geometry of the wellbore, by explicitly writing the dependency of the unknowns in the radial direction. For each model, the fluxes are approximated by conservative Raviart-Thomas elements, ensuring natural transmission conditions at the interface. An analysis of the resulting mixed formulations is carried out and the well-posedness of the semi-discretized problems is established. Then, numerical results including real study cases are presented. Finally, a global coupling approach of the two models is exposed

Full textIndustrial photocatalysis applications requires further research to control and design photocatalytic reactors. The micro structuring of reactors is an innovative solution. It increases the catalytic efficiency by improving the contact of the pollutant with the catalyst. Thesis aim concerned the destruction of a model pollutant, salicylic acid, with deposited catalyst (TiO2) at the bottom of a microchannel. The research is based on experiments and simulations to predict the photocatalytic degradation for a given reactor configuration. In our experimental conditions of low flow, an axial dispersion and a concentration gradient between the catalyst surface and the reaction medium have been demonstrated. We have shown that the gradient of velocity is more pronounced in low cross section microreactors. This gradient allows the formation of recirculation zones near the catalytic surface thus creating favorable conditions for contact between the pollutant and the catalytic surface. Using numerical soft, we have simulated the reaction of photocatalytic degradation to represent our experimental results. On a one hand, the role of diffusion to the catalytic surface has been demonstrated. On the other hand, numerical simulation has allowed to establish a relationship between the Sherwood number as a function of Reynolds number, Schmidt and the hydraulic diameter of the microchannel. This relationship is used to estimate the mass transfer constant to represent correctly the photocatalytic degradation
