Full textThis study focused on developing a better understanding of granular dynamics in pebble bed reactor cores through experimental work and computer simulations. The work completed includes analysis of pebble motion data from three scaled experiments based on the annular core of the Pebble Bed Fluoride Salt-Cooled High- Temperature Reactor (PB-FHR). The experiments are accompanied by the development of a new discrete element simulation code, GRECO, which is designed to offer a simple user interface and simplified two-dimensional system that can be used for iterative purposes in the preliminary phases of core design. The results of this study are focused on the PB-FHR, but can easily be extended for gas-cooled reactor designs.
Experimental results are presented for three Pebble Recirculation Experiments (PREX). PREX 2 and 3.0 are conventional gravity-dominated granular systems based on the annular PB-FHR core design for a 900 MWth commercial prototype plant and a 16 MWth test reactor, respectively. Detailed results are presented for the pebble velocity field, mixing at the radial zone interfaces, and pebble residence times. A new Monte Carlo algorithm was developed to study the residence time distributions of pebbles in different radial zones. These dry experiments demonstrated the basic viability of radial pebble zoning in cores with diverging geometry before pebbles reach the active core.
Results are also presented from PREX 3.1, a scaled facility that uses simulant materials to evaluate the impact of coupled fluid drag forces on the granular dynamics in the PB-FHR core. PREX 3.1 was used to collect first of a kind pebble motion data in a multidimensional porous media flow field. Pebble motion data were collected for a range of axial and cross fluid flow configurations where the drag forces range from half the buoyancy force up to ten times greater than the buoyancy force. Detailed analysis is presented for the pebble velocity field, mixing behavior, and residence time distributions for each fluid flow configuration.
The axial flow configurations in PREX 3.1 showed small changes in pebble motion compared to a reference case with no fluid flow and showed similar overall behavior to PREX 3.0. This suggests that dry experiments can be used for core designs with uniform one-dimensional coolant flow early in the design process at greatly reduced cost. Significant differences in pebble residence times were observed in the cross fluid flow configurations, but these were not accompanied by an overall horizontal diffusion bias. Radial zones showed only a small shift in position due to mixing in the diverging region and remained stable in the active core. The results from this study support the overall viability of the annular PB-FHR core by demonstrating consistent granular flow behavior in the presence of complex reflector geometries and multidimensional fluid flow fields.
GRECO simulations were performed for each of the experiments in this study in order to develop a preliminary validation basis and to understand for which applications the code can provide useful analysis. Overall, the GRECO simulation results showed excellent agreement with the gravity-dominated PREX experiments. Local velocity errors were found to be generally within 10-15% of the experimental data. Average radial zone interface positions were predicted within two pebble diameters. GRECO simulations over predicted the amount of mixing around the average radial zone interface position and therefore can be treated as a conservative upper bound when used in neutronics analysis. Residence time distributions from the GRECO velocity data based on the Monte Carlo algorithm closely matched those derived from the experiment velocity statistics. GRECO simulation results for PREX 3.1 with coupled drag forces showed larger errors compared to the experimental data, particularly in the cases with cross fluid flow. The large discrepancies suggest that GRECO results in systems with coupled fluid drag forces cannot be used with high confidence at this point and future development work on coupled pebble and fluid dynamics with multidimensional fluid flow fields is required.

Full textGranular crystals are spatially periodic structures of elastic particles arranged in crystal lattices. The interactions between particles take place via their elastic interconnections, which are of much smaller dimensions and weights than the beads. This induces propagation of elastic waves in granular structures at significantly slower velocities than in the individual grains. In addition, due to the existence of non-central shear forces, rotations of particles can be initiated, leading to extra phononic modes in the crystals. In the manuscript, wave dynamics in two-dimensional monolayer granular crystals with either out-of-plane or in-plane particle motion is studied. The phononic properties are investigated, including Dirac points, zero-frequency modes, zero-group-velocity modes and their transformation into slow propagating phononic modes. Furthermore, in the presence of edges/boundaries, zero-frequency and extremely slow elastic edge waves can be also predicted in mechanical granular honeycomb crystals (granular graphene). In addition, topological properties of rotational edge waves in a granular graphene are theoretically demonstrated. By inducing topological transition, which turns the topological order of granular graphene from trivial to nontrivial, topological edge transport in the granular graphene can be observed. The developed theories could promote the potential applications of designed granular structures with novel elastic wave propagation properties

Full textMateriais granulares, por sua enorme gama de aplicaçõesindustriais (da indústria alimentícia à astrofísica), vêm sendo cada vez mais estudados durante as últimas duas décadas. No entanto, muito da descrição física inerente ao comportamento deste tipo de material ainda elude os cientistas, tornando este um campo particularmente rico de investigação. Dentre as questões insolutas, estão algumas de crescente interesse, como os mecanismos de fluxo e transporte de grãos, que descrevem fenômenos como a difusão correlacionada e a formação de bandas de cisalhamento, por exemplo. Através de modelos fenomenológicos e matemáticos, este trabalho visa melhorar a compreensão destes fenômenos e dos mecanismos por trás deles, em especial a participação fundamental dos arcos de forças formados pelos grãos. Através de um modelo fenomenológico razoavelmente simples e de simulações computacionais, o papel dos arcos fica evidente ao se observar, nas simulações, o comportamento característico da formação de bandas de cisalhamento, reproduzindo resultados experimentais e previsões de modelos teóricos encontrados na literatura. Concomitantemente, foi desenvolvido um modelo matemático teórico para se descrever a difusão correlacionada de grãos, fenômeno que acreditamos estar baseado no mesmo princípio de transporte através dos arcos, reproduzindo o comportamento qualitativo de simulações computacionais.
Granular materials, due to their huge amount of industrial applications (from food industry to astrophysics), have been the object of an increasing number of studies throughout the last couple of decades. Much of the physical description concerning the behaviour of this kind of material, however, still eludes scientists, turning this field of research into a particularly rich one. Among the unsolved questions in this area there are some of growing interest, such as the mechanisms of grains transport and flux, which describe phenomena like correlated diffusion and the formation of shear bands, for example. By means of phenomenological and mathematical models, this work tries to improve the understanding of these phenomena and the mechanisms behind them, particularly the fundamental role of arches of forces created by the grains. Using a relatively simple phenomenological model and computer simulations, the role of arches becomes evident when it is observed, in the simulations, the characteristic behaviour of shear bands formation, reproducing experimental results and the predictions of theoretical models found in the literature. Simultaneously, a theoretical mathematical model was developed to describe granular correlated diffusion, a phenomenon we believe is based on the same principle of transportation by means of arches, reproducing the qualitative behaviour of computer simulations.
