Texto completo da fonteThe goal of this work is to contribute to a better understanding of gas-particle flows. We have developed a code based on the Eulerian-Lagrangian approach in a two-dimensional configuration. This method allows us to follow the trajectory of each particle in the riser in order to study the discrete behavior of the solid phase. We have investigated the gas-solid flow both in diluted and dense fluidized beds. In the first case, we studied the clustering behavior of the particles caused by hydrodynamics and modified by collision characteristics. In the second, we investigated a dense bed in order to get a better understanding of the bubble formation, which is linked to porosity perturbations within the bed

Texto completo da fonteMicro-fluidized bed (MFB) exhibits great advantages such as a large specific contact surface, a fast dissipation of heat (ideal for exothermic reactions) and better mass and heat transfers, but suffers from difficulties in precise control and shows strong frictional wall effect. Present study was conducted experimentally and numerically to understand fundamental hydrodynamics in MFBs. Experimental work was carried out in four MFBs of 20-4 mm compared to two relatively large beds of 100-50 mm using three types of particles (B347: 347 μm, 2475 kg/m3; B105: 105 μm, 8102 kg/m3; A63: 63.8μm, 2437 kg/m3). The ratio of static bed height (Hs) to bed diameter (Dt) was set between 1-4. Mechanical vibration was applied to the 4 mm bed. A new method for flow regimes diagnosis was developed based on pressure fluctuation analyses, which mainly include calculating the standard deviation, autocorrelation function, probability density function, power spectral density function and time-frequency analysis. Numerical simulations were performed under Eulerian-Eulerian framework in 2D. Six flow regimes were identified: fixed bed, bubbling, bubbling/slugging, slugging, slugging/turbulent and bubbling/turbulent. Partial fluidization is encountered at Hs/Dt=1-2 while slugging prevails quickly after minimum fluidization at Hs/Dt=3-4. In the 4 mm bed, fluidization of B347 particles show better fluidization quality, while an increase in Umf is observed for B105 and A63 particles. Mechanical vibration reduces partial fluidization, thus resulting in larger ΔP and smaller Umf. A larger Umb and a delayed Uc were obtained as well. Results by simulations agree reasonably well with experimental data

Texto completo da fonteEulerian two fluid approach is generally used to simulate gas-solid flows in industrial circulating fluidized beds. Because of limitation of computational resources, simulations of large vessels are usually performed by using too coarse grid. Coarse grid simulations can not resolve fine flow scales which can play an important role in the dynamic behaviour of the beds. In particular, cancelling out the particle segregation effect of small scales leads to an inadequate modelling of the mean interfacial momentum transfer between phases and particulate shear stresses by secondary effect. Then, an appropriate modelling ac counting for influences of unresolved structures has to be proposed for coarse-grid simu-lations. For this purpose, computational grids are refined to get mesh-independent result where statistical quantities do not change with further mesh refinement for a 3-D peri-odic circulating fluidized bed. The 3-D periodic circulating fluidized is a simple academic configuration where gas-solid flow conducted with A-type particles is periodically driven along the opposite direction of the gravity. The particulate momentum and agitation equations are filtered by the volume averaging and the importance of additional terms due to the averaging procedure are investigated by budget analyses using the mesh independent result. Results show that the filtered momentum equation of phases can be computed on coarse grid simulations but sub-grid drift velocity due to the sub-grid correlation between the local fluid veloc- ity and the local particle volume fraction and particulate sub-grid shear stresses must be taken into account. In this study, we propose functional and structural models for sub- grid drift velocity, written in terms of the difference between the gas velocity-solid volume fraction correlation and the multiplication of the filtered gas velocity with the filtered solid volume fraction. Particulate sub-grid shear stresses are closed by models proposed for single turbulent flows. Models’ predictabilities are investigated by a priori tests and they are validated by coarse-grid simulations of 3-D periodic circulating, dense fluidized beds and experimental data of industrial scale circulating fluidized bed in manner of a posteriori tests

Texto completo da fonteThe objective of this work is to conceive, develop, implement and to optimize a continuous technology allowing a good control of the precipitation reactions, fast chemical process, giving birth to a solid phase. This precipitor is a multipurpose engine with fluidized bed which did not make the same great strides like fluidized bed crystallizers. Two experimental approaches were adopted : (1) the study of the mixing phenomena of the reagents and (2) the study of the influence of the operating conditions on the precipitation of a model product. The model product selected for this study is the calcite, the polymorphic most stable phase of calcium carbonate which has three polymorphs: vaterite, aragonite and calcite. The latter is obtained by the precipitation reaction between the calcium chloride and sodium carbonate solutions at a temperature of 20° C and a complexing agent (sodium citrate) to have the required crystalline form. A kinetic study was undertaken for the determination of the nucleation and crystalline growth kinetics of calcite in citrate medium. The fluidized bed reactor, having a volume of 10 L, consisted of two zones: cylindrical for fluidization and classification of the particles and cylindro-conical for decantation, was conceived at the Chemical Engineering Science Laboratory (LSGC). The study of mixing phenomena, performed using the decoloration acid-base reaction and the hydrodynamic study, carried out using suspensions of glass microballs, made it possible to develop and optimize this multipurpose reactor. The feasibility of the precipitation of calcite in a fluidized bed was then checked. The experiments carried out in the presence of an important solid content made it possible to decrease supersaturation and to support the crystalline growth. The precipitate obtained presents a relatively narrow size distribution and the particle shape is appreciably spherical. Lastly, the modelling tests of the fluidized bed reactor were undertaken to carry out simulations using the FLUENT commercial computer code
