CFD Hydrodynamics Analysis of Syngas Flow in Slurry Bubble Column
In this paper, a CFD model of syngas flow in slurry bubble column was developed. The model is based on an Eulerian-Eulerian approach and includes three phases: slurry of solid particles suspended in paraffin oil and syngas bubbles. Numerical calculations carried out for catalyst particles, bubble coalescence and breakup included bubble-fluid drag force and interfacial area effects. Also, the ef...

متن کاملCFD Simulation of Bubbly Flow Through a Bubble Column
In this investigation, CFD simulation is presented to study the hydrodynamic of bubbly flow and mass transfer in bubble column using EulerianEulerian Multifluid approach with a standard kε turbulence model. unsteady state method for modeling the multiphase flow and mass transfer from air to de-aerated water and the column hydrodynamics. Understanding the complexity of the fluid dynamics and mas...
متن کاملEfficient numerical techniques for flow simulation in bubble column reactors
A dynamic Euler-Euler model for gas-liquid flows subject to mass transfer and simultaneous chemical reaction is assembled. The bubble size distribution is computed from an equation governing the evolution of average bubble mass. Highperformance finite element tools for numerical solution of the problem at hand are discussed. Computational results for the chemisorption of CO2 into NaOH shed some...
متن کاملFlow Simulation in a 2D Bubble Column with the Euler-lagrange and Euler-euler Method
Method: The presented EL method uses the open access software OpenFOAM to solve bubble dynamics with bubble interactions computed via Monte Carlo methods. The estimated bubble size distribution and the predicted hold-up are compared with experimental data and other simulative EE work with a reasonable consensus for both. Benchmarks with state of the art EE simulations shows that the EL approach...
