Book Synopsis Micromixing in a Single Feed Semibatch Precipitation Process by : R. Gupta
Download or read book Micromixing in a Single Feed Semibatch Precipitation Process written by R. Gupta and published by . This book was released on 1998 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precipitation processes are initiated by chemical reactions, which lead to the generation of high supersaturations followed by nucleation and growth of the precipitated particle. The precipitation reactions are very fast and are thereby influenced by mixing. Micromixing is desxribed in terms of engulfment of the environment by a mixed-precipitation zone. Macromixing is accounted for by updating the environment. The effects of various operating conditions on the particle size distribution of barium sulfate were investigated and verified experimentally in an 18-L Rushton type semibatch reactor.

Book Synopsis Computational Fluid Dynamics Simulation of Precipitation Processes by : Liguang Wang
Download or read book Computational Fluid Dynamics Simulation of Precipitation Processes written by Liguang Wang and published by . This book was released on 2004 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: First, an experimental and computational investigation of the effects of local fluid shear rate on the aggregation and breakage of [Difference] 10 [Mu]m latex spheres suspended in an aqueous solution undergoing laminar and turbulent Taylor-Couette flow was carried out, according to the following program. First, computational fluid dynamics (CFD) simulations were performed and the flow field predictions were validated with data from particle image velocimetry experiments. Subsequently, the quadrature method of moments (QMOM) was implemented into the CFD code to obtain predictions for mean particle size that account for the effects of local shear rate on the aggregation and breakage. These predictions were then compared with experimental data for latex sphere aggregates (using an in-situ optical imaging method) and with predictions using spatial average shear rates. The mean particle size evolution predicted by CFD and QMOM using appropriate kinetic expressions that incorporate information concerning the particle morphology (fractal dimension) and the local fluid viscous effects on aggregation collision efficiency matches well with the experimental data. Second, CFD simulation of turbulent reactive precipitation in a poorly micromixed plug-flow reactor has been investigated in this work. The predictions of multi-environment and transported PDF models are compared. For the first time, DQMOM is formulated and applied to approximate the composition PDF transport equation. When properly chosen, the resulting DQMOM correction terms enforce agreement between selected lower-order moments of the mixture-fraction PDF and the exact moment transport equations. Likewise, for reacting scalars, the multi-environment PDF model provides a closure for the chemical source term, and the DQMOM correction terms enforce the correct behave of the lower-order moments under the influence of turbulent diffusivity. Results for reactive precipitation show that the DQMOM-IEM model agrees closely with a transported PDF model. Since the multi-environment PDF model is much less computationally intensive than the transported PDF model, it is easy and extremely promising to couple the simple Eulerian-based multi-environment PDF models with a commercial CFD code for realistic industrial problems. Third, a novel algorithm, in-situ adaptive tabulation, has been implemented in a CFD code for the integration of reactive precipitation. A speed-up of [Difference]10 was achieved.
Book Synopsis Pore Scale Geochemical Processes by : Carl Steefel
Download or read book Pore Scale Geochemical Processes written by Carl Steefel and published by Walter de Gruyter GmbH & Co KG. This book was released on 2015-09-25 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This RiMG (Reviews in Mineralogy & Geochemistry) volume includes contributions that review experimental, characterization, and modeling advances in our understanding of pore-scale geochemical processes. The volume had its origins in a special theme session at the 2015 Goldschmidt Conference in Prague. From a diversity of pore-scale topics that ranged from multi-scale characterization to modeling, this work summarizes the state-of-the-science in this subject. Topics include: modification of thermodynamics and kinetics in small pores. chemo-mechanical processes and how they affect porosity evolution in geological media. small angle neutron scattering (SANS) techniques. how isotopic gradients across fluid–mineral boundaries can develop and how these provide insight into pore-scale processes. Information on an important class of models referred to as "pore network" and much more. The material in this book is accessible for graduate students, researchers, and professionals in the earth, material, environmental, hydrological, and biological sciences. The pore scale is readily recognizable to geochemists, and yet in the past it has not received a great deal of attention as a distinct scale or environment that is associated with its own set of questions and challenges. Is the pore scale merely an environment in which smaller scale (molecular) processes aggregate, or are there emergent phenomena unique to this scale? Is it simply a finer-grained version of the "continuum" scale that is addressed in larger-scale models and interpretations? The scale is important because it accounts for the pore architecture within which such diverse processes as multi-mineral reaction networks, microbial community interaction, and transport play out, giving rise to new geochemical behavior that might not be understood or predicted by considering smaller or larger scales alone.
