Full textOil based drilling fluids are used in offshore drilling operations to cool and lubricate the drilling bit, to transport the cuttings to the surface and to maintain the hydrostatic pressure in the well. With the increasing depth of offshore drilling, the thermodynamic conditions (high pressure and low temperature) are favourable to the formation of gas hydrates in the water-in-oil emulsions contained in the fluids. High pressure Differential Scanning Calorimetry (DSC) is a proven technique for the study of thermodynamic equilibrium of the system gas - water - hydrate. DSC was chosen to study the kinetics of hydrate formation because it is particularly well adapted to complex dispersed media. A study was curried out at variable pressure from 11 to 40 MPa and at variable sub-cooling degree from 14 to 30 K. Hydrate formation kinetics was studied in four fluids of different compositions. Performed experiences highlight the effect of different kinetic parameters. T he use of classic models allowed representing the experimental results for low and high driving forces. Furthermore, we developed a kinetic model which combines the theory of the crystallization, the statistical aspect of nucleation and the mass balance on different components of the drilling fluid

Full textAblative thermal protection systems, commonly used in space industry, are usually made of composite materials. The degradation of these materials in surface allows to protect essential parts against severe aerothermal fluxes. In the literature, lots of different systems are described they are constituted of different type of matrix and reinforced by several kind of fibers. The diversity of the existing thermal protection systems raises the question of the influence of the composition of the materials on the thermal and ablative performances. The developed scientific approach is based on an experimental procedure coupled with the development of a numerical simulation. The material characterization is based on three experimental steps : the thermo-chemical behavior of the materials is investigated with TGA, TMA and DSC experiments, the thermal behavior under a severe flux is evaluated by an experimental bench equipped with an oxyacetylenic torch ; finally, the ablative behavior is characterized with a small jet-nozzle impacting the sample with a severe aerothermal flux. In parallel to the experimental characterization, a numerical simulation modeling of the ablative and thermal behavior of composite materials is developed. Links existing between the thermal behavior and the ablation resistance have been demonstrated. Degradation scenarios have been proposed thanks to the combined analysis of the experimental results at each stage of the characterization. Parameters controlling the ablation have been identified, the major impact of the porosity has been particularly demonstrated

Full textThe aim is to investigate and model the mechanical behaviour of a semi-crystalline thermoplastic (PolyAmide 11) far above Tg. A strain-rate independent loading curve (asymptotic curve) is observed below a critical strain-rate depending on temperature during tension and torsion tests. Such observations are consistent with a relaxed state of the rubbery amorphous phase. Nevertheless, the unloading curve is hysteretic and creep or stress relaxation responses are observed when loading is interrupted along the asymptotic curve. Microstructure analyses (DSC and X-ray) indicate that local reorganizations, involving crystalline phase, occur along the asymptotic curve. These conclusions on micro-mechanisms are used to build constitutive laws in a mechanical model. These micro-mechanisms affect the material stiffness and the relaxed state of the amorphous viscosity. This model is tested on simple loading cases
