Full textThe aim of this study concerns the use of numerical methods for the resolution of the Reynolds Averaged Navier Stokes equations adapted to the simulation of the cooling of the trailling edge of a stator in a HP turbine. The elsA solver developped at ONERA, is used with a four steps Runge Kutta time discretisation scheme and a Jameson centered space discretisation scheme. Turbulence is simulated either through the Michel, Spalart-Allmaras, k-l, k-w, k-e and ASM models. Some simulations of the flow in a bidimensional stator, with and without cooling (which is realized with the Chimera technique), are carried out. It validated this technique. The tridimensional simulation of a single cooled stator is also realized. Finally two steady computations, without and with cooling, and an unsteady computation without cooling are carried out on a high pressure turbine stage. These results make it possible to determine the effect of the cooling on the flow in a turbine stage

Full textPlant cells, like all eukaryotes, possess a complex endomembrane system defines cell compartments and assures secretion. Ln addition to certain organization common to eukaryotes, plant secretory systems exhibit organizational and structural specificities. This work aimed to investigate the part of genetically distinct and adaptive-response secretory states. Two experimental models were studied: the digestive glands of the carnivorous plant Dionaea muscipula and proliferating BY-2 cells. The secretory glands of Dionaea are a typical plant example of massive protein secretion under a tight stimulation. Transmission electron microscopy (TEM) allowed us to observe an activation of Golgi apparatus (GA) after stimulation by prey, which profoundly remodelled the cell surface and cell wall. The role of these changes in the induction of a water flux is discussed. Study of BY-2 cells had two main axes. The first was to analyze GA evolution along the cell cycle and any duplication phase, combining cytometry and fluorescence microscopy. Our results suggest an increase of GA mass during interphase. This increase seems to reflect a response to secretion needs of the growing cell rather than a regulated step of the progressing cell cycle. The second axis was to study brefeldin A (BFA) effects on cell cycle progression. BFA blocked the cell cycle at the end of mitosis, following aberrant positioning of the nucleus in daughter cells after division following disorganization of the reticulum (ER), critical to nuclear envelope reformation after mitosis. Overall, this work has shown the extreme variability of the endomembrane system in plant cells and the adaptability of both the GA and ER

Full textThe present work aims at studying the cooling system used in cars engine to ensure piston thermo mechanical resistance by numerical simulation. Most of actual engines use an oil jet cooling system coupled with 'cocktail shaking' to extract heat from piston. This cooling method brings into play a two-phase incompressible turbulent flow in a mobile environment, due to motion of pistons in the cylinder. The need today for more effective cooling of pistons involves an accurate understanding of the physical mechanisms which are concerned. Modeling could be a good way to achieve it. The idea is to support the engine design process to account for advanced technologies to improve turbine or engine performances, less fuel burn and green house gases. In the present work, a numerical model dedicated to the simulation at small scale of oil/air two-phase flows and related heat transfers is proposed to characterize the cooling of engine elements under fragmented jet impact

Full textUnder hypothetical loss-of-coolant accident conditions, fuel cladding tubes made of zirconium alloys can be exposed to steam at high temperature (up 1 200°C) before being cooled and then quenched in water. In some conditions, after burst occurrence the cladding can rapidly absorb a significant amount of hydrogen (secondary hydriding), up to 3 000wt.ppm locally, during steam exposition at HT.The study deals with the effect, poorly studied up to date, of high contents of hydrogen on the metallurgical and mechanical properties of two zirconium alloys, Zircaloy-4 and M5®, during and after cooling from high temperatures, at which zirconium is in its β phase. A specific facility was developed to homogeneously charge in hydrogen up to ~3 000wt.mass. cladding tube samples of several centimeters in length. Phase transformations, chemical element partitioning and hydrogen precipitation during cooling from the β temperature domain of zirconium were studied by using several techniques, for the materials containing up to ~3 000wt.ppm of hydrogen in average: in-situ neutron diffraction upon cooling from 700°C, X-ray diffraction, µ-ERDA, EPMA and electron microscopy in particular. The results were compared to thermodynamic predictions. In order to study the effect of high hydrogen contents on the mechanical behavior of the (prior-)β phase of zirconium, axial tensile tests were performed à various temperatures between 20 and 700°C upon cooling from the β temperature domain, on samples with mean hydrogen contents up to ~3 000ppm-mass.The results show that metallurgical and mechanical properties of the (prior-)β phase of zirconium alloys strongly depend on temperature and hydrogen content
