An accurate measurement of total temperature in turbomachinery flows remains critical for component life models and cycle performance optimization. While many techniques exist to measure these flows, immersed thermocouple based probes remain highly desirable due to well established practices for probe design and implementation in typical industrial flow applications. However, as engine manufacturers continue to push towards higher maximum cycle temperatures and smaller flow passages, the continued use of these probes requires new probe designs considering both improved sensor durability and measurement accuracy. Increased maximum temperatures introduce many challenges for total temperature measurements using conventional immersed probes, including increased influences of conduction, convection, and radiation heat transfer between the sensor, fluid and the surroundings due to large thermal gradients present in real turbomachinery systems. While these effects have been thoroughly described and quantified in the past, the available design models are very limited to specific geometries and flow conditions. In this Dissertation, a more fundamental understanding of the flow behavior around typical vented shield style total temperature probes as a function of probe geometry and operating condition is gained using results from high-fidelity Computational Fluid Dynamics simulations with Conjugate Heat Transfer (CHT) capabilities. Results were further quantified in the form of new empirical correlations necessary for rapid thermal performance evaluations of current and future probe designs. Additionally, a new mixed-fidelity or Reduced Order Modeling (ROM) technique was developed which allows the coupling of high fidelity surface heat transfer data from CFD with a generalized form of the 1-D conducting solid equations for readily predicting the impact of radiation environment and transient errors on sensor performance.

Повний текст джерелаThis thesis validates the concept of mixed electron/proton ceramic conductors to be used as anode materials for intermediate temperature steam electrolyzer. The materials developed are based on cobaltites of alkaline-earth metals and rare earth elements commonly used for their high electronic conductivity in the temperature range of 300-600°C. The stability of each material has been assessed during 350h in air and moist air. After checking the chemical compatibility with the BaZr0.9Y0.1O3 electrolyte material, eight compositions have been selected: BaCoO3, LaCoO3, Sr0.5La0.5CoO3, Ba0.5La0.5CoO3, GdBaCo2O5, NdBaCo2O5, SmBaCo2O5 and PrBaCo2O5. The thermal evolution of the oxygen stoichiometry of each material was determined by coupling iodometric titration and TGA in dry air. TGA in moist air has allowed determining the optimum temperature range for which proton incorporation is possible and maximized. Proton incorporation profiles have been determined on two cobaltites using SIMS and nuclear microanalysis in the ERDA configuration. Deuterium diffusion coefficients have been determined confirming the proton mobility in these materials. Under moist air, NdBaCo2O5 is shown to incorporate rapidly a significant number of protons that spread homogeneously within the material bulk. Anode microstructure optimization has allowed reaching at 450°C and 600°C total resistance values on symmetrical cell highly promising

Повний текст джерелаDans ce cadre, le but de nos recherche a été de concevoir de nouveaux matériaux de cathode pour pile PCFC présentant de bonnes propriétés de conduction mixte ionique et électronique ainsi qu'une activité catalytique élevée vis-à-vis de la réaction de réduction de l'oxygène, entre 400 et 600°C. Plusieurs matériaux à conduction mixte ont été synthétisés à l'ICMCB, notamment des perovskites et des oxydes de structure de type Ruddlesden-Popper (en particulier les oxydes A2MO4+). Des analyses thermogravimétriques ont été réalisées pour étudier la stabilité de ces phases sous air humide, ainsi qu'une éventuelle insertion d'eau dans la structure. Des demi-cellules symétriques ont été élaborées pour les caractérisations éléctrochimiques par spectroscopie d'impédance complexe et voltampérométrie (mesures de résistances spécifiques de surface, courbes de polarisation cathodique).
Les caractérisations physico-chimiques et électrochimiques ont permit de sélectionner les meilleurs composés et ont conduit à la réalisation de la première monocellule PCFC utilisant le matériau de cathode Pr2NiO4+. Des densités de puissance de 100 mW/cm² ont été mesurées pour une température de fonctionnement de 600°C.

Повний текст джерелаThis work reports on the design, synthesis and characterization of novel anilate-based functional molecular materials showing luminescent, magnetic and/or conducting properties. The family of anilate ligands comprises several derivatives obtained by introducing various substituents (H, F, Cl, Br, I, CN, etc.) at the 3 and 6 positions of the common 2,5-dihydroxy-1,4-benzoquinone framework. Among the anilate ligands, the only known heterosubstituted anilate with Cl/CN substituents at the 3,6 positions, ClCNAn2-, have been selected for preparing a novel family of 2D layered coordination polymers (2D CP) with both 3d metal ions and 4f lanthanide ions, through a general and straightforward synthetic strategy. i) Mixed-valence FeIIFeIII 2D CP, formulated as [TAG][FeIIFeIII(ClCNAn)3], containing, the tris(amino)-guanidinium (TAG) cation for the first time in such 2D networks has been synthesized and thoroughly characterized. ii) 2D CPs based on NIR-emitting lanthanides (YbIII, NdIII, ErIII) and the ClCNAn2- ligand, have been prepared and characterized. These layered compounds were exfoliated to nanosheets, by sonication-assisted solution synthesis. Time-resolved photoluminescence studies performed on both the bulk and nanosheets are also highlighted. iii) Novel family of heteroleptic 2D CPs based on NIR-emitting lanthanides and mixed ligands (ClCNAn2- and carboxylate ligands (DOBDC and F4-BDC)), were prepared and characterized. vi) Novel family of 2D CPs based on DyIII and ClCNAn2- were prepared in order to investigate their magnetic properties. v) Furthermore, the ability of anilate ligands to work as components of BEDT-TTF- based molecular conductors have been demonstrated through the synthesis, via electrocrystallization technique. vi) П-d hybrid multifunctional paramagnetic molecular conductors BEDT-TTF and [Fe(ClCNAn)3]3-) were also studied

Inspired by the fact that OH- has a very high mobility in water, highly conductive OH⁻conducting membranes were developed for alkaline water electrolysis. The membranes were semi-interpenetrating networks of crosslinked poly(vinyl alcohol) (PVA) and a polycation miscible with PVA. It is analogous to aqueous strong base solution. The polycation is a OH- containing polymer; PVA solvates this polycation and facilitates the ion conduction via Grotthuss mechanism. The membrane with proper composition has an exceptionally high OH⁻ conductivity of 151 mS/cm, 6.51 times as high as the commercial membrane Neosepta AHA. At the same time, the hydrogen bonds and covalent crosslinks in the system give this membrane a high tensile strength of 41 MPa in the wet state, 46% higher than the Neosepta AHA membrane. Insight in the ion conduction mechanism was gained by spectroscopic studies and the measurement of OH- conduction activation energy.
This material system is also highly anion perm-selective, a feature critical to sustaining the pH gradient in bipolar membrane based artificial photosynthesis devices. A highly transparent mixed proton and electron conducting membrane was developed. The Nafion and reduced graphene oxide (rGO) were chosen as the proton conducting polymer matrix and the electrically conductive filler respectively. The filler has a high aspect ratio. As predicted by simulations, it will have low percolation threshold if homogeneously dispersed. To achieve this homogeneity, water-aided mixing was employed followed by fast freezing in liquid nitrogen. Though rGO is a light absorber, the extremely low percolation threshold (0.1%) allows us to achieve sufficient electrical conductivity with only a small volume fraction of rGO. Therefore, the membrane was highly transparent in addition to its ability to conduct both electrons and protons.
Detailed modeling of the energy loss from conduction, light absorption, and gas crossover was conducted, showing that this material system is promising for the artificial photosynthesis application.
