Повний текст джерелаFull Scale extrapolation of pressure measurements obtained with model scale tanks. The work presented in this manuscript aims at a better comprehension of the hydroelastic phenomena occurring in the Liquified Natural Gas tanker at full scale during sloshing impacts. The existing 2D Smooth Particles Hydrodynamics (SPH) solver has then been enhanced with inspiration of Finite-Volume formalism especially around the works linked with the Riemann solvers. The fluid SPH code is then naturally extended to a structural code. The coupling procedure between the two existing codes is then naturally obtained which is the main advantage of using the SPH method in a fluid-structure context. Some very classical benchmarks are developed in comparison with analytical codes, Finite Elements and experiments. The classical case of hydrodynamic impact is detailed for a rigid structure. The structural code is validated on several benchmarks representatives of different modes which can be simulated with the SPH method. The case of the hydrodynamic impact is presented in a fluid-structure coupled way with a solid mass and then with a plate. A chapter is dedicated to experimental comparisons. The last part of this thesis is dedicated to a more industrial use of the developed code. An idealisation of the sloshing impact by a hydrodynamic impact is given. Some other idealisations are proposed to study the problem further. Some LNG insulation impacts are presented and allow a better comprehension of the hydroelastic phenomena when idealisation is still correct

Повний текст джерелаThe motion of a liquid-filled microcapsule flowing in a microchannel is a complex problem tosimulate. Two innovative reduced-order data-driven models are proposed to replace the Fluid Structure Interaction (FSI) model using a collected database from high-fidelity simulations. The objective is to replace the existing Full Order Model (FOM) with a fast-simulation model that can simulate the capsule deformation in flow at a low cost in terms of time and calculation. The first model consists in building from a space-time-parameter datacube a reduced model to simulate the deformation of the microcapsule for any admissible configuration of parameters. Time evolution of the capsule deformation is treated by identifying the nonlinear low-order manifold of the reduced variables. Then, manifold learning is applied using the Diffuse Approximation (DA) method to predict capsule deformation for a query configuration of parameters and a chosen time discretization. The second model is based on rewriting the FSI model under the form of a reduced-order dynamic system. In this latter, the spectral displacement and velocity coefficients are related through a dynamic operator to be identified. To determine this operator, we suggest the use of a dynamic mode decomposition approach. Numerical validations prove the reliability and stability of the two new models compared to the high order model. A software application has been developed to explore the capsule deformation evolution for any couple of admissible parameters

Повний текст джерелаIn this thesis, a fully compressible real-fluid model has been developed, in which the two-phase characteristics are obtained using a tabulated vapor-liquid equilibrium (VLE) approach. This tabulated multicomponent real-fluid model (RFM) is proposed to overcome most limitations and make real-fluid simulations affordable. Basically, the RFM model consists of four balance equations: mass density, partial species density, momentum, and energy. The thermodynamic properties of the mixture are calculated as a function of temperature (T), pressure (P), and compositions(Y) based on different equations of state (EoS). This is carried out using the IFPEN-Carnot thermodynamic library which generates a 3D-table with (T,P,Y) as inputs. This look-up table is generated using a computationally efficient isothermal-isobaric (TPn)-flash, thereby avoiding the costlier iterative isochoric-isoenergetic (UVn)-flash employed in previous works. It specifically includes different thermodynamic outputs such as sound speed, heat capacity, and transport properties. The RFM model, along with the 3D tabulation method, has been implemented in the CONVERGE CFD solver. All thermal and transport properties are linearly interpolated using the updated (T,P,Y) during the simulation. First, various studies have been done for the refinement, and grid in-dependency of the thermodynamic tables, especially near the thermodynamic phase boundary using uniform and nonuniform grids. These studies have demonstrated that nonuniform grids, like octree and quadtree, is costly compared to the uniform approach. Therefore, uniform tabulation coupled with IFPEN's shared memory technique proved to be the most appropriate approach for tabulation, for the targeted industrial studies. Next, the present work has also investigated the robustness and accuracy of the proposed RFM model and the tabulation methodologies in conjunction with two different modified numerical schemes, a modified PISO and modified SIMPLE algorithms, adapted for the current real fluid modeling approach. Then, the proposed RFM model has been successfully applied to different academic and industrial applications to investigate subcritical classical evaporation/condensation and transcritical mixing characteristics. Among them, two industrially important test cases for which recent experimental results are available have been simulated and analyzed to validate the RFM model.1- Simulation of a conventional cryogenic injection of liquid nitrogen coaxially with a hot hydrogen jet was performed using thermodynamic tables generated by two different equations of state: Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK).2- Simulation of the interaction between phase transition and turbulent fluid dynamics for subcritical and supercritical multi-species jets using different turbulence models including large-eddy simulations (LES Sigma and Smagorinsky) models as well as a Reynolds Averaged Navier-Stokes (RANS K-ε).The numerical results were found to be in good agreement with the available experimental data and published numerical studies, which also showed the relevance of the LES approach associ-ated with the Sigma model for these very complex two-phase flows. Finally, numerical results showed that the tabulation method improves the liquid-vapor equilibrium (VLE) efficiency for real fluid modeling and provides a mean to study and understand the structure of subcritical and transcritical liquid-gas interfaces revealing the hydro-thermodynamic characteristics of the multicomponent jet mixture

Повний текст джерелаCurrently, most heat pump(HP) manufacturers provide coefficient of performance (COP) values obtained in laboratories under standardized controlled operating conditions. These COP values are not necessarily representative of those obtained on-field. A promising method, referred to as the performance assessment method, that measures heat pump performances in-situ based on compressor energy balance, was presented by Tran et al. (2013). The method determines refrigerant mass flow rate and has the capability of measuring performances of various HP types, such as air-to-air, as well as more complex refrigeration cycles. The method abstains from intrusive measurements, and is, therefore, perfectly suitable for in-situ measurements.As shown in the work of Tran et al. (2013), compressor heat losses account for 40% in the final uncertainty of performance values obtained with the performance assessment method. The objective of this thesis is to establish a rather simplified measurement method, in terms of instrumentation, that is used to determine compressor heat losses in-situ. For this purpose two detailed numerical models for assessing the temperature fields of the scroll and rotary compressor shells were developed. Experimental measurements obtained with the help of compressor manufacturer, Mitsubishi Heavy Industries (MHI), are used to validate and calibrate the numerical models. The developed numerical models allow to define two different measurement protocols for both compressors. Established compressor heat loss protocol for rotary compressor is then integrated in the performance assessment method and the obtained heating capacities are compared with reference measurements in an experimental test bench in EDF Lab Les Renardières

Повний текст джерелаCertaines applications, comme la suture d'organe, mettent en jeu plusieurs modèles dynamiques liés ensemble. Pour ce type de simulation, nous proposons une architecture logicielle permettant de simuler des articulations d'objets quelconques (rigides ou déformables) quel que soit le formalisme physique employé pour chacun d'eux. Cette proposition logicielle trouve diverses applications notamment en simulation chirurgicale mais permet aussi de simuler dynamiquement toute articulation d'objets hétérogènes. Certaines manipulations requièrent une souplesse du modèle à des endroits précis, sachant que ces zones peuvent se déplacer lors d'une simulation, par exemple pendant le serrage d'un noeud. Pour cela, nous proposons une multirésolution géométrique et mécanique sur notre modèle qui vise à adapter localement sa résolution afin qu'il puisse s'adapter aux interactions tout en offrant des bonnes performances générales en calcul. On concentre alors le plus gros du temps de calcul sur les zones d'intérêt et on limite ce temps dans les autres zones du modèle. Un critère d'adaptation de la résolution en fonction de la courbure est proposé. Cette technique est particulièrement adaptée à la simulation de noeuds en permettant à la spline d'augmenter le nombre de degrés de liberté et ainsi en lui fournissant une grande souplesse de définition géométrique dans la zone de serrage
