CFD Simulation of Parameters Affecting Hydrodynamics of Packed Beds: Effects of Particle Shape, Bed Size, and Bed Length
Packed bed reactors have many applications in different industries such as chemical, petrochemical, and refinery industries. In this work, the effects of some parameters such as the shape and size of particles, bed size, and bed length on the hydrodynamics of the packed beds containing three spherical, cylindrical, and cubic particles types are investigated using CFD. The effect of the combinat...
متن کاملNumerical simulation of effect of non-spherical particle shape and bed size on hydrodynamics of packed beds
Fluid flow has a fundamental role in the performance of packed bed reactors. Some related issues, such as pressure drop, are strongly affected by porosity, so non-spherical particles are used in industry for enhancement or creation of the desired porosity. In this study, the effects of particle shape, size, and porosity of the bed on the hydrodynamics of packed beds are investigated with three ...
متن کامل3D Simulation of Packed Particle Bed and Transport Properties Prediction for Product Optimization through Virtual Experiments
Porous media are heterogeneous systems. The microstructures of the pore spaces influence their transport properties. A quantitative geometrical characterization of the pore space is crucial for accurate prediction of porous media transport. Thus, a 3D simulation of porous media was developed based on randomly packed glass beads. Unconsolidated porous media are reconstructed through Monte Carlo ...

15 صفحه اولModeling and Simulation for Dynamics of Packed Bed Adsorption
Understanding the dynamics of fixed-bed adsorption columns for modeling is a demanding task due to the strong nonlinearities in the equilibrium isotherms, interference effects of competition of solutes for adsorbent sites, mass transfer resistances between fluid phase and solid phase, and fluid-dynamic dispersion phenomena. The interplay of these effects produces steep concentration fronts, whi...
