Pełny tekst źródłaThe amount of residual gas trapped in the cylinder of an internal combustion engine has a huge influence on its behavior (combustion, efficiency, emission,..), in particular for spark ignition engines. Nowadays, it is possible to modify this amount, in particular with variable valve train. However, the experimental assessment of residual gas content and its evaluation with numerical simulation are still challenging. The objective of this study is to propose new methodologies to improve these two aspects. A bibliographical survey is first proposed to give state of the art. It gathers the main parameters influencing residual gas content, the effects of residual gas on engine behavior, experimental procedures and numerical models available for residual gas content estimation. An original system is then developed to measure the amount of residual gas with an in-cylinder gas sampling triggered at the end of compression stroke. The results, obtained on the whole operating map of a naturally aspirated automotive spark ignition engine, are analyzed with respect to engine rotation speed, load and cam phaser position (intake side). Finally, various modeling of valve overlap with a 0D/1D approach are assessed. The standard “perfect mixing” assumption is not fully satisfactory, so that new assumptions are proposed and tested. A hybrid approach combining “perfect mixing” and “perfect displacement” allows for improved agreement with experiments, after calibration of a model parameter with respect to engine rotation speed and load

Pełny tekst źródłaPermeability is a parameter that may indirectly influence the durability of concrete structures by governing the rate of penetration of aggressive substances responsible for degradation under a pressure gradient. The aim of this thesis is to study the interaction between the crack opening and the transfer of fluids in concrete of the Brazilian splitting tensile test (BSTT). Herein, the influence of aggregates size and volume fraction on hydro-mechanical properties of concrete is investigated. This study consists of two parts: the numerical and the experimental one. The first one focuses on the meso-scale modeling of a heterogeneous material like a concrete, which may be characterized by two features: multi-phase behavior and 3D crack propagation. The numerical study deals therefore with the coupling between crack opening and gas permeability according to a developed hydro-mechanical model at a meso-scale. The objective of the second, experimental part, is to provide data for numerical models and to validate the latter. This work is carried out on mortar specimens with 3 different aggregate sizes, submitted to gas transfer during a BSTT. The numerical meso-scale model is based upon a 3D lattice approach to represent the heterogeneity of the material and the failure mechanism of concrete. This model considers concrete as a two-phases material in which aggregates melt within a cement paste. Because a non-adapted meshing process was used to mesh the microstructure, a weak discontinuity was introduced in the first enhancement of the kinematics. The second enhancement of kinematics introduced here is the displacement discontinuity (strong) to represent crack opening (discontinuous displacement-field). The hydro-mechanical model represents the transport of fluids (gases) through the concrete, depending on Darcy's law for a uncracked section (porosity) and Poiseuille's law for a cracked section (laminar flow). In this model, the interaction between the crack opening, obtained from the mechanical model (meso-scale), and the gas permeability is investigated. The experimental work is presented for the validation of the hydro-mechanical model. The numerical results show good agreement with some previous experimental and theoretical studies

Pełny tekst źródłaGalaxy clusters are the most massive gravitationally bound structures of the universe, and the history of their formation is a direct consequence of the evolution of the large scale structure of the universe. As a result, studying these objects allows to constrain cosmological parameters, which are at the core of the models describing the evolution of our universe. The use of galaxy clusters as cosmological probes relies on the observation of their matter content, and in particular their content in ordinary matter, or "baryons". Baryonic matter is mainly present under the form of stars in galaxies and of gas inside the intra-cluster medium. However, baryons in galaxy clusters are subject to astrophysical effects which will impact their properties. These effects need to be analysed in detail in order to obtain an in depth understanding of these objects and to properly constrain the conditions that dictated their formation, their assembly, and their current properties.I propose in this thesis a thorough analysis of baryons and of their effects in clusters, from galaxies to the gas, using observations in optical, X-ray, and millimeter wavelengths. A first part of my study is focused on galaxies and the analysis of their properties from optical spectroscopy, inside two triple-cluster systems discovered by the Planck satellite. I show that these two systems appear as triple only due to projection effects on the line of sight, and that they are actually constituted of isolated clusters lying at several hundreds of megaparsecs from each other, except for a cluster pair. I show in addition that inside the most distant cluster, several galaxies are still star-forming, contrary to the galaxies in lower redshift systems. This may be the sign of a transition between a regime of high star formation in high redshift systems and the low star formation regime which is observed in low redshift clusters.The remainder of my work is dedicated to the gas fraction in galaxy clusters, in particular to constrain the bias which appears following the assumption of hydrostatic equilibrium when measuring cluster masses. This "hydrostatic bias", if poorly understood, is responsible for biased cosmological constraints from galaxy clusters. By using gas masses and total masses computed under the assumption of hydrostatic equilibrium in X-ray observations, I computed the gas fraction of 120 galaxy clusters, and constrained the value of the hydrostatic bias, as well as its evolution with mass and redshift. I show that the evolution of the bias is degenerate with cosmological parameters, leading to aberrant cosmological constraints when assuming the wrong evolution for the bias. I however show that these results are dependent on the considered sample, with trends of the bias changing depending on the mass and redshift selection of the sample. In any case, whatever the sample selection I find that my results are in agreement with a collection of other measurements of the bias using other methods, as well as with predictions from hydrodynamical simulations. These results are nevertheless in tension with the value of the bias preferred by the combination of cosmic microwave background observations with galaxy cluster number counts.Finally I combined gas fraction data of clusters with cluster number counts from millimeter wavelengths observations. This allowed me to study the constraints on cosmological parameters that this combination allowed, as well as the constraints on the hydrostatic bias. I show that adding gas fraction to cluster counts allows to break degeneracies that exist between the hydrostatic bias and cosmological parameters, without any prior on the bias.My work thus allowed to improve the understanding of the astrophysical properties of baryons in galaxy clusters. I notably highlighted some of the links and correlations between astrophysical effects and cluster cosmology, allowing for an accurate and robust description of these objects

Cenker, Emre. "Imaging measurements of soot particle size and soot volume fraction with laser-induced incandescence at Diesel engine conditions". Thesis, Châtenay-Malabry, Ecole centrale de Paris, 2014. http://www.theses.fr/2014ECAP0049/document.
Pełny tekst źródłaThis work focuses on measurements of soot particle size and volume fraction at Diesel engine conditions. A combination of laser-Induced incandescence (LII) imaging, line-Of-Sight laser extinction, soot pyrometry, and transmission electron microscopy (TEM) measurements of thermophoretically-Sampled soot was used. Particle sizing strategies were developed with LII model for the analysis of particle-Size poly-Dispersity with time-Resolved LII signal that is suitable for point-Wise measurements at atmospheric pressure, and for spatially-Resolved characterization with two-Time-Step LII imaging. Measurements were performed with these strategies in a flame at atmospheric pressure and in Diesel engine combustion to investigate their applicability. Additional measurements were performed for temperature and soot volume fraction.A novel method, called two-Exponential reverse fitting (TERF), is introduced to extract information about the size distribution. The method is based on mono-Exponential fits to the LII signal decay at a delayed time. It approximates the particle-Size distribution as a combination of one large and one small mono-Disperse equivalent mean particle size and does not require a distribution assumption. It also provides a ratio of the contribution of both size classes. The systematic error caused by de-Scribing LII signals by mono-Exponential decays was calculated as less than 2% for LII signals simulated for mono-Disperse aggregated soot with heat-Up temperatures for which evaporation is negligible. The method was applied to LII data acquired in a laminar non-Premixed ethylene/air flame at various heights above the burner. The particle size of the large particle-Size class evaluated with the method showed good consistency with TEM results, however the size of the small particle-Size class and its relative contribution could not be compared due to insufficient information in the TEM results for small particles. Simultaneous line-Of-Sight laser extinction measurements and LII imaging were performed to de-Rive the soot volume fraction in a high-Temperature high-Pressure constant-Volume pre-Combustion vessel under the Engine Combustion Network’s (ECN) "Spray A" conditions with parametric variations of gas temperature and composition. Extinction measurements were used to calibrate LII images for quantitative soot distribution measurements. OH-Chemiluminescence imaging was used to determine the lift-Off length, and used to interpret the soot measurements. Maximum soot volume fractions around 2–3 ppm were obtained at the nominal ambient temperature defined for Spray A (i.e. 900 K) that rise to 12 ppm at elevated temperature (1030 K). Variations of ambient temperature and oxygen concentration were carried out showing effects on soot formation and oxidation that are consistent with the literature.The method for particle-Size imaging is based on evaluating gated LII signals acquired with two cameras consecutively after the laser pulse and using LII modeling to deduce particle size from the ratio of local signals. A strategy was developed with a model-Based analysis: the dependence of LII particle-Size imaging on the assumed boundary conditions was identified such as bathgas temperature, pressure, particle heat-Up temperature, thermal accommodation coefficients, and soot morphology. Various laser-Fluence regimes and gas pressures were considered. Effects of laser attenuation were evaluated. A combination of one detection gate starting with the particle-Heating and the other starting with 11 ns delay with twice as long gate width was found to provide the highest sensitivity for particle sizing at 60 bar. The optimum gate delays for different pressures were calculated. The effects of timing jitter for laser pulse and poly-Dispersity were investigated. Systematic errors in pyrometry imaging at 60 bar was evaluated. [...]

Pełny tekst źródłaCrystallization of hydrates during oil production is a major source of hazards, mainly related to flow lines plugging after hydrate agglomeration. During the petroleum extraction, oil and water circulate in the flow line, forming an unstable emulsion. The water phase in combination with light hydrocarbon components can form hydrates. The crystallization of hydrates has been extensively studied, mainly at low water content systems. However, as the oil field matures, the water fraction increases and can become the dominant phase, a system less known in what concerns hydrate formation. Actually, several techniques can be combined to avoid or remediate hydrate formation. Recently, a new class of additives called Low Dosage Hydrate Inhibitor (LDHI) started to be studied, they are classified as Kinetic Hydrate Inhibitors (KHI-LDHI) and Anti-Agglomerants (AA-LDHI).This work is a parametric study about hydrate formation from emulsion systems ranging from low to high water content, where different flow rates and the anti-agglomerant presence were investigated. The experiments were performed at the Archimède flow loop, which is able to reproduce deep sea conditions. The goal of this study is enhancing the knowledge in hydrate formation and comprehending how the dispersant additive acts to avoid agglomeration. For this matter, it was developed a crystallization topological model for the systems without and with additive. A technique to determine the system continuous phase and a mechanism of the anti-agglomerant action from the chord length measurements were also proposed

Pełny tekst źródłaIncludes bibliographical references (p. 37).
Residual gas tests were done on a 2.4 liter commercial engine to find a correlation for the effect on spark timing on residual gas fraction. The tests were done by sampling the charge mass during a non-firing cycle through a small hole into cylinder 4. The residual gas fraction was determined by measuring the CO2 content of the sample. The experiments were conducted for a variety of different spark timing and valve timing settings. Since the data was taken over a limited range, a physical basis for a correlation was developed. Following the approach used in a previous modeling effort, the residual gas fraction was modeled as the sum of two contributing factors: backflow from the exhaust port to the cylinder during valve overlap and gas trapped inside the cylinder at the time of intake valve open. Additionally, the phenomenon of choked backflow was introduced in the model. Based on the data, a correlation was developed that estimates the residual gas fraction as a function of: intake to exhaust pressure ratio (Pi/Pe), valve profile, engine speed, compression ratio, and spark timing.

Pełny tekst źródłaThe residual gas fraction is an important parameter to get good performance with high efficiency and low emissions in the HCCI-engine.
The goal in this thesis is to formulate an algorithm for estimation of the residual gas fraction based on the cylinder pressure. The estimation is improved if also the exhaust gas temperature is used together with the cylinder pressure.
The formulated algorithm has then been tested on data from a single cylinder engine running in HCCI-mode during steady state conditions. An error of 4% was noted compared with the residual gas fraction obtained from simulations.
The thesis also investigates the effects of some possible error sources.
