Bourne, Emily. "Non-uniform numerical schemes for the modelling of turbulence in the 5D GYSELA code". Electronic Thesis or Diss., Aix-Marseille, 2022. http://www.theses.fr/2022AIXM0412.
Pełny tekst źródłaThis thesis lies within the context of fusion plasma simulations and it has a double objective: (i) develop new scalable numerical methods, adapted to the semi-lagrangian scheme used in the 5D gyrokinetic GYSELA code, capable of solving the problem of large fluctuations and temperature variations at the edge of the plasma, and (ii) take into account more realistic magnetic configurations than the concentric circles currently simulated by the code. I present a new approach for quadrature using splines, which limits the condition number for the procurement of such quadrature coefficients. I present a local spline method where derivatives are transported between patches, and show its stability for semi-lagrangian advection. The semi-lagrangian method based on non-uniform splines on a Vlasov-Poisson 1D-1V model is used for studies of the plasma sheath. The existing VOICE code (which is a mini version of GYSELA), designed to study such problems, has been modified and optimised on a GPU to operate on a non-uniform mesh. Co-variant and contra-variant transformation matrices of a new realistic magnetic configuration were derived and implemented in the code to allow the 5D Vlasov equations to take into account new geometry. The inclusion of this new magnetic configuration has been successfully numerically validated on the linear benchmarks used for GAM studies. In parallel, a test platform for the 2D Poisson solver was developed in order to numerically compare this spline finite elements solver to two other multi-grid solvers: (i) a solver using finite volumes on a uniform cartesian mesh with embedded boundaries, and (ii) a solver using finite differences on a logical mesh

Pełny tekst źródłaDu point de vue théorique, la turbulence plasma est décrite par les équations gyrocinétiques, un ensemble d équations aux dérivées partielles non linéaires couplées. Par suite des très différentes échelles spatiales mises en jeu dans des conditions expérimentales réelles, une simulation numérique directe et complète (DNS) de la turbulence gyrocinétique est totalement hors de portée des plus puissants calculateurs actuels, de sorte que démontrer la faisabilité d’une alternative permettant de réduire l’effort numérique est primordiale. En particulier, les simulations de grandes échelles (”Large-Eddy Simulations” - LES) constituent un candidat pertinent pour permettre une telle r éduction. Les techniques LES ont initialement été développées pour les simulations de fluides turbulents à haut nombre de Reynolds. Dans ces simulations, les plus grandes échelles sont explicitement simulées numériquement, alors que l’influence des plus petites est prise en compte via un modèle implémenté dans le code.
Cette thèse présente les premiers développements de techniques LES dans le cadre des équations gyrocinétiques (GyroLES). La modélisation des plus petites échelles est basée sur des bilans d’énergie libre. En effet, l’energie libre joue un rôle important dans la théorie gyrocinétique car elle en est un invariant non lin éaire bien connu. Il est démontré que sa dynamique partage de nombreuses propriétés avec le transfert d’energie dans la turbulence fluide. En particulier, il est montré l’existence d’une cascade d énergie libre, fortement locale et dirigée des grandes échelles vers les petites, dans le plan perpendiculaire â celui du champ magnétique ambiant.
La technique GyroLES est aujourd’hui implantée dans le code GENE et a été testée avec succès pour les instabilités de gradient de température ionique (ITG), connues pour jouer un rôle crucial dans la micro-turbulence gyrocinétique. A l’aide des GyroLES, le spectre du flux de chaleur obtenu dans des simulations à très hautes résolutions est correctement reproduit, et ce avec un gain d’un facteur 20 en termes de coût numérique. Pour ces raisons, les simulations gyrocinétiques GyroLES sont potentiellement un excellent candidat pour réduire l’effort numérique des codes gyrocinétiques actuels.
/ Anomalous transport due to plasma micro-turbulence is known to play an important role in confinement properties of magnetically confined fusion plasma devices such as ITER. Indeed, plasma turbulence is strongly connected to the energy confinement time, a key issue in thermonuclear fusion research. Plasma turbulence is described by the gyrokinetic equations, a set of nonlinear partial differential equations. Due to the various scales characterizing the turbulent fluctuations in realistic experimental conditions, Direct Numerical Simulations (DNS) of gyrokinetic turbulence remain close to the computational limit of current supercomputers, so that any alternative is welcome to decrease the numerical effort. In particular, Large-Eddy Simulations (LES) are a good candidate for such a decrease. LES techniques have been devised for simulating turbulent fluids at high Reynolds number. In these simulations, the large scales are computed explicitly while the influence of the smallest scales is modeled.
In this thesis, we present for the first time the development of the LES for gyrokinetics (GyroLES). The modeling of the smallest scales is based on free energy diagnostics. Indeed, free energy plays an important role in gyrokinetic theory, since it is known to be a nonlinear invariant. It is shown that its dynamics share many properties with the energy transfer in fluid turbulence. In particular, one finds a (strongly) local, forward (from large to small scales) cascade of free energy in the plane perpendicular to the background magnetic field.
The GyroLES technique is implemented in the gyrokinetic code Gene and successfully tested for the ion temperature gradient instability (ITG), since ITG is suspected to play a crucial role in gyrokinetic micro-turbulence. Employing GyroLES, the heat flux spectra obtained from highly resolved direct numerical simulations are recovered. It is shown that the gain of GyroLES runs is 20 in terms of computational time. For this reason, Gyrokinetic Large Eddy Simulations can be considered a serious candidate to reduce the numerical cost of gyrokinetic simulations.

Pełny tekst źródłaTurbulenz ist in astrophysikalischen Plasmen allgegenwärtig. Viele solche Systeme weisen eine sogenannte Kreuz-Helizität auf, also eine von Null verschiedene Korrelation zwischen Geschwindigkeits- und Magnetfeld-Fluktuationen. In einer anisotropen Magnetfeldgeometrie, z. B. im Sonnenwind oder dem interstellaren Medium, deutet die Kreuz-Helizität auf ein Ungleichgewicht zwischen Alfven-Wellen, die sich in Richtung des gemittelten Feldes ausbreiten, und solchen, die in die Gegenrichtung propagieren, hin. Obwohl dieses Ungleichgewicht die stochastische Beschleunigung und Streuung, die geladene Teilchen in einem Plasma erfahren, dramatisch beeinflusst, wurde es in bisherigen numerischen Studien über turbulenten Teilchentransport gemeinhin außer Acht gelassen. In dieser Arbeit nun werden rechnergestützte Simulationen von magnetohydrodynamischer Turbulenz präsentiert, in denen die Energie und die Kreuz-Helizität kontrolliert werden können, ohne jedoch kinetische oder magnetische Helizität als unerwünschte Nebenwirkung zu erzeugen. Die Stärke des mittleren Magnetfeldes bestimmt dabei die Anisotropie des Gleichgewichtszustandes. Die Simulationen erfüllen in allen Parameterbereichen die Vorhersagen, die theoretische Modelle für realistische Plasmaturbulenz treffen. Die Diffusion kosmischer Strahlung in turbulenten Plasmen wird häufig im Rahmen der quasilinearen Theorie unter Heranziehung eines stark vereinfachten Turbulenzspektrums berechnet. Indem die Trajektorien von Testteilchen in dynamischen Turbulenzsimulationen mit Kreuz-Helizität berechnet werden, lassen sich quasilineare Ergebnisse für die Beschleunigungsrate geladener Teilchen nachprüfen. Theorie und numerische Simulation stimmen für Teilchen mit der Alfven-Geschwindigkeit gut überein, solange resistive Effekte vernachlässigt werden können. Weiterhin werden aus der quasilinearen Theorie berechnete Diffusionskoeffizienten mit numerisch ermittelten Streuraten für Testteilchen nach einer Gyroperiode in stark anisotropen Feldkonfigurationen verglichen, wobei der Schwerpunkt erneut beim Einfluss der Kreuz-Helizität liegt. Für alle verwendeten Werte der Kreuz-Helizität ergibt sich eine exzellente Übereinstimmung zwischen Simulationsergebnis und Vorhersage. Schließlich wird die Rolle des magnetischen Moments, einer adiabatischen Invarianten bei der Bewegung geladener Teilchen in einem Magnetfeld, für die Streuung über Zeitskalen von mehreren Gyroperioden erläutert.

Pełny tekst źródłaPlasma-assisted combustion has received increasing attention in both plasma and combustion communities. Nanosecond Repetitively Pulsed (NRP) discharges are a promising and efficient technique to initiate and control combustion processes particularly when conventional ignition systems are rather ineffective or too energy costly. Even though a promising technique, the phenomena occurring in NRP discharges-assisted combustion are still poorly understood. The numerical studies presented in the literature are limited to 1-D and 2-D simulations in quiescent conditions. The problem complexity increases in practical configurations as ignition phenomena are also controlled by the flow and mixing field characteristics in and around the discharge channel. Direct Numerical Simulations (DNS) is a powerful research tool to understand these plasma/combustion/flow interactions. However, the computational cost of fully coupled detailed non-equilibrium plasma and combustion chemistry, and high Reynolds number simulations is prohibitive. This thesis presents a model to describe the effects of non-equilibrium plasma discharges in the set of equations governing the combustion phenomena. Based on the results reported in the literature, the model is constructed by analyzing the channels through which the electric energy is deposited. The two main channels by which the electrons produced during the discharge impact the reactive mixture are considered: 1) the excitation and the subsequent relaxation of the electronic states of nitrogen molecules, which leads to an ultrafast increase of the gas temperature and dissociation of species; and 2) the excitation and relaxation of vibrational states of nitrogen molecules which causes a much slower gas heating. This high level model of NRP discharges allows DNS studies of plasma-assisted combustion / ignition in high turbulent Reynolds number. The complex physics underlying plasma-assisted ignition by multiple discharges in both quiescent and turbulent flow conditions are discussed in the present thesis

Pełny tekst źródłaUnderstanding impurity transport in the core of tokamak plasmas is central to achieving controlled fusion. Indeed impurities are ubiquitous in these devices and their presence in the core are detrimental to plasma confinement (fuel dilution, Bremsstrahlung). Recently, specific attention was given to the convective mechanism related to the gradient of the toroidal rotation to explain experimental flat/hollow impurity profiles in the plasma core. In this thesis, up-to-date modelling tools (NEO for neoclassical transport and GKW for turbulent transport) including the impact of toroidal rotation are used to study both the neoclassical and turbulent contributions to impurity fluxes. A comparison of the experimental and modelled carbon density peaking factor (R/LnC) is performed for a large number of baseline and hybrid H-mode plasmas (increased confinement regimes) with modest to high toroidal rotation from the European tokamak JET. Confrontation of experimental and modelled carbon peaking factor yields two main results. First roto-diffusion is found to have a nonnegligible impact on the carbon peaking factor at high values of the toroidal rotation frequency gradient. Second, there is a tendency to overpredict the experimental R/LnC in the core inner region where the carbon density profiles are hollow. This disagreement between experimental and modelled R/LnC, closely related to the collisionality, is also observed for the momentum transport channel which hints at a common parallel symmetry breaking mechanism lacking in the simulations

Pełny tekst źródłaSteady-state operations of the next-generation fusion device ITER will require the development of reliable numerical tools to estimate key engineering parameters suitable for technological constraints at reasonable computational cost.So-called transport codes fulfil this requirement since they rely on 2D fluid equations averaged over time fluctuations, similarly to Reynolds Averaged Navier-Stokes models commonly used for engineering applications in the neutral fluid community. Furthermore, transport codes can gather most of the physical ingredients ruling the edge plasma behaviour, as well as realistic magnetic topology and wall geometry. However, their predictability is limited by a crude description of turbulent fluxes perpendicular to the magnetic field lines. In the plasma community, a special concern is devoted to acquire a detailed understanding of these fluxes, since they strongly impact on the power extraction and the confinement of plasma over extended periods of time. In transport codes though, turbulent fluxes, which are assumed diffusive, are crudely determined by either homogeneous, or ad-hoc diffusive coefficients, or feedback-loop procedures applied a-posteriori on experimental data.Motivated by these issues, in this work we introduce step-by-step a new approach with the aim to self-consistently estimate the distribution of turbulent fluxes in transport codes, when steady-state plasmas are concerned. The underlying strategy is inspired by the work done from the 60’s in neutral turbulence and adapted here to plasma for fusion applications.The first key concept is the Boussinesq assumption. It consists in assuming a colinearity between the Reynolds stress tensor - which represents the contribution of turbulence to the mean flow - and the mean rate of strain tensor - expressed by the gradient of the mean velocity through a coefficient: the so-called eddy-viscosity. The second concept is to express this new eddy viscosity coefficient as a function of characteristic turbulence quantities. We have focused here on the most popular in Computational Fluid Dynamics, the κ-ε model, where transport equations for the averaged kinetic turbulent energy and the turbulence dissipation rate are designed semi-empirically. Steady-state κ and ε allow for a self-consistent estimation of the eddy-viscosity coefficient, thus including the impact of turbulence in steady-state mean flows. We propose a κ-ε -like model where two transport equations for turbulent kinetic energy and its dissipation rate are derived algebraically, including the physics of the linear interchange instability. For the numerical implementation, we exploit the flexibility of the transport package SolEdge2D-EIRENE, developed for many years through the collaboration of the IRFM at the CEA and the laboratory M2P2 at Aix-Marseille University.Since the new model is semi-empirical, it presents some free parameters to be closed. In this work, we have proposed different approaches. In particular, in order to increase the predictive capabilities of the model, a reference scaling law for the width of the heat-flux profile in the scrape-off layer has been assumed, empirically determined from the experimental measurements of the outer target heat load in various machines. The new model is integrated in SolEdge2D-EIRENE for simulations with diverted plasma in TCV and WEST-like geometries, for L-mode discharges. Steady-state results are discussed and shown to favourably compare with experimental data at both the outer mid-plane and the outer divertor. Moreover, self-consistent distributions of diffusivities are shown to exhibit poloidal asymmetries consistently with the ballooned distribution of cross-field transport due to the interchange instability and observed at the same conditions in both first-principle codes and experiments
Ben, Hassan Saïdi Ismaïl. "Numerical simulations of the shock wave-boundary layer interactions". Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLS390/document.
Pełny tekst źródłaSituations where an incident shock wave impinges upon a boundary layer are common in the aeronautical and spatial industries. Under certain circumstances (High Mach number, large shock angle...), the interaction between an incident shock wave and a boundary layer may create an unsteady separation bubble. This bubble, as well as the subsequent reflected shock wave, are known to oscillate in a low-frequency streamwise motion. This phenomenon, called the unsteadiness of the shock wave boundary layer interaction (SWBLI), subjects structures to oscillating loads that can lead to damages for the solid structure integrity.The aim of the present work is the unsteady numerical simulation of (SWBLI) in order to contribute to a better understanding of the SWBLI unsteadiness and the physical mechanism causing these low frequency oscillations of the interaction zone.To perform this study, an original numerical approach is used. The one step Finite Volume approach relies on the discretization of the convective fluxes of the Navier Stokes equations using the OSMP scheme developed up to the 7-th order both in space and time, the viscous fluxes being discretized using a standard centered Finite-Difference scheme. A Monotonicity-Preserving (MP) constraint is employed as a shock capturing procedure. The validation of this approach demonstrates the correct accuracy of the OSMP scheme to predict turbulent features and the great efficiency of the MP procedure to capture discontinuities without spoiling the solution and with an almost negligible additional cost. It is also shown that the use of the highest order tested of the OSMP scheme is relevant in term of simulation time and accuracy compromise. Moreover, an order of accuracy higher than 2-nd order for approximating the diffusive fluxes seems to have a negligible influence on the solution for such relatively high Reynolds numbers.By simulating the 3D unsteady interaction between a laminar boundary layer and an incident shock wave, we suppress the suspected influence of the large turbulent structures of the boundary layer on the SWBLI unsteadiness, the only remaining suspected cause of unsteadiness being the dynamics of the separation bubble. Results show that only the reattachment point oscillates at low frequencies characteristic of the breathing of the separation bubble. The separation point of the recirculation bubble and the foot of the reflected shock wave have a fixed location along the flat plate with respect to time. It shows that, in this configuration, the SWBLI unsteadiness is not observed.In order to reproduce and analyse the SWBLI unsteadiness, the simulation of a shock wave turbulent boundary layer interaction (SWTBLI) is performed. A Synthetic Eddy Method (SEM), adapted to compressible flows, has been developed and used at the inlet of the simulation domain for initiating the turbulent boundary layer without prohibitive additional computational costs. Analyses of the results are performed using, among others, the snapshot Proper Orthogonal Decomposition (POD) technique. For this simulation, the SWBLI unsteadiness has been observed. Results suggest that the dominant flapping mode of the recirculation bubble occurs at medium frequency. These cycles of successive enlargement and shrinkage of the separated zone are shown to be irregular in time, the maximum size of the recirculation bubble being submitted to discrepancies between successive cycles. This behaviour of the separation bubble is responsible for a low frequency temporal modulation of the amplitude of the separation and reattachment point motions and thus for the low frequency breathing of the separation bubble. These results tend to suggest that the SWBLI unsteadiness is related to this low frequency dynamics of the recirculation bubble; the oscillations of the reflected shocks foot being in phase with the motion of the separation point

Pełny tekst źródłaIn this thesis, the interaction between tokamak edge plasma and resonant magnetic perturbation (RMPs) is studied. It is mainly used to mitigate quasi-periodic relaxations in enhanced confinement regime. This regime allows to obtain good conditions for nuclear fusion. Introduction of a RMP in a tokamak plasma has been observed to modified the magnetic topology at the edge and decrease the relaxation amplitude up to complete suppression. Previous works studied the RMP effect on a plasma with relaxations, via numerical simulations. The model used for that consider the electrostatic approximation, where the magnetic topology does not evolve in time. In this thesis, the study is done with an edge plasma model taking into account magnetic fluctuations via the numerical code EMEDGE3D. This code has been modified to include the resonant magnetic perturbation. Comparison with reduced models has been carried out on the RMP penetration and the effect of sheared velocity on it. Then a RMP has been induced in a stable plasma, with or without imposed sheared rotation. A condition on the sheared velocity has been identified to avoid the screening effect, that would prevent the RMP penetration, analytically and in numerical simulations. This works has been repeated in a turbulent plasma in presence or not of transport barrier (sheared velocity). The turbulent plasma generate an effective RMP amplification, while the transport barrier is affected by locked convective cells due to the RMP
