10th International Conference on Circulating Fluidized Beds and Fluidization Technology - CFB-10
Industrial scale bubbling fluidized bed simulations were carried out within the Kinetic Theory of Granular Flows (KTGF). The KTGF was applied within two different modelling frameworks, the traditional Two Fluid Model (TFM) and a new approach in the form of the Dense Discrete Phase Model (DDPM), in order to identify any differences in performance. Only the DDPM was able to attain fully grid independent results for industrial scale 2D simulations. In fact, the performance was sufficiently good to enable the completion of reasonably affordable full 3D simulations. These simulations revealed some differences between 2D and 3D, but the global system …

Effects Of Tethering A Multistate Folding Protein To A Surface, Shuai Wei, Thomas A. Knotts Iv
Faculty Publications
Protein/surface interactions are important in a variety of fields and devices, yet fundamental understanding of the relevant phenomena remains fragmented due to resolution limitations of experimental techniques. Molecular simulation has provided useful answers, but such studies have focused on proteins that fold through a two-state process. This study uses simulation to show how surfaces can affect proteins which fold through a multistate process by investigating the folding mechanism of lysozyme (PDB ID: 7LZM). The results demonstrate that in the bulk 7LZM folds through a process with four stable states: the folded state, the unfolded state, and two stable intermediates. The …
Development Of A Phase Separation Model For A Biodiesel Reactor, Lu Han
Development Of A Phase Separation Model For A Biodiesel Reactor, Lu Han
Honors Scholar Theses
The goal of this work is to establish a phase separation model for a biodiesel system, for the purpose of modeling a continuous flow multiphase biodiesel reactor. The Cahn-Hilliard theory is applied for a ternary system of two immiscible components and a third partially miscible component. The results of this work shows that phase field theory can be applied in phase modeling of a biodiesel system, and further investigations are required to develop a comprehensive biodiesel reactor model.

Comparison Of Entrainment Rate In Acrylonitrile Reactors Using Plant Data And Cfd Simulations, S. Moffatt, S. Ramchandran, P. Zhao, K. Williams
10th International Conference on Circulating Fluidized Beds and Fluidization Technology - CFB-10
Accurate entrainment rates are important in fluidized bed reactors for several reasons, including determination of cyclone loadings and efficiencies, sizing of diplegs, and inputs to population balance models. Entrainment correlations exist in the literature and from other sources to predict entrainment rates from fluidized beds, but they can vary by orders of magnitude. In addition, many correlations do not take into account effects of internals which are present in many types of industrial reactors. A study was undertaken to better understand entrainment rates from Sohiotype acrylonitrile fluidized bed reactors containing catalyst classified as a Geldart type A powder. As part …

The Computational Fluid Dynamics (CFD) approach was used to simulate sorption of CO2 using solid sorbents in the riser section of a circulating fluidized bed. The simulation results were compared with the experimental data of Korea Institute for Energy Research (KIER) for continuous CO2 sorption using potassium carbonate in a circulating fluidized bed system.

10th International Conference on Circulating Fluidized Beds and Fluidization Technology - CFB-10
Two-phase granular systems are commonly encountered in industry, and fluidized beds are particularly important due to their excellent heat and mass transfer characteristics. Here, we critically evaluate the differences between two modelling strategies, Euler-Euler and Euler-Lagrangian models. Euler-Euler simulations were performed using MFIX and an in-house code was used for Euler-Lagrangian simulations. A 2D bed of width, height and transverse thickness of respectively, 0.2 m, 0.5 m and 0.01 m, served as a test case. The settled bed height was H0 = 0.2 m. Particles of density ρ = 1000 kg/m³ and diameter dp = 1.2 mm were fluidized with …

Particle-Fluid Flow Simulations Of An Fcc Regenerator, Sam Clark
10th International Conference on Circulating Fluidized Beds and Fluidization Technology - CFB-10
A particle-fluid flow simulation of a commercial-scale fluidized catalytic cracking unit has been conducted. The simulation was full-scale, three-dimensional, and with complex internal geometries. The focus of the computational model was to predict wear on internal structures. The geometry of the particle feed pipe was found to cause asymmetric flow of high-speed gas which led to significant wear.

This paper discusses the influence of fines on the size of bubbles moving through a 23 cm ID fluidized bed of Geldart A particles imaged with an X-ray Tomographic Scanner. In earlier work [1], the bubble distribution in a fluidized bed of Geldart B particles was shown. The current study using Geldart A particles is more challenging to the reconstruction algorithm, since there are more bubbles, and they are smaller in size. We study the influence of adding fines (i.e. particles <= 45 micron) to the system. When adding a mass fraction of fines of 24%, we find a decrease of the average bubble of 40% of the size for the original powder, in line with earlier results from pressure probes and optical probes [2]. We find that the entire distribution of the bubble sizes shifts to smaller values.

A partitioned fluidized bed gasifier has been developed for improving coal gasification performance. The basic concept is to divide a fluidized bed into two parts, a gasifier and a combustor, by a partition. Char is burnt in the combustor and generated heat is supplied to the gasifier by solid mixing. Therefore, solid mixing should be maximized whereas gas mixing between syngas and the combusted gas should be minimized. In this study, gas and solid mixing behaviors were verified in cold model acrylic beds. For monitoring solid mixing behavior, transient temperature trends in the beds were analyzed. A heat source and …
