Euler-Euler Large Eddy Simulation of a Square Cross-Sectional Bubble Column Using the Neptune_CFD Code

Flow 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...

Large Eddy Simulation of the Gas-Liquid Flow in a Square Cross-sectioned Bubble Column

Column N.G. Deen, T. Solberg and B.H. Hjertager Chem. Eng. Lab., Aalborg Univ. Esbjerg; Niels Bohrs Vej 8; DK-6700 Esbjerg; Denmark Abstract In this work the use of large eddy simulations (LES) in numerical simulations of the gas-liquid flow in bubble columns is studied. The Euler-Euler approach is used to describe the equations of motion of the two-phase flow. It is found that, when the drag, ...

Towards Large Eddy Simulation of Non-Homogeneous Particle Laden Turbulent Gas Flows Using Euler-Euler Approach

A Large Eddy Simulation approach for Eulerian-Eulerian dispersed two-phase flow is presented. It is shown that not only a Sub-Grid Scales term modeling the unresolved field in the mesoscopic momentum transport equation of the dispersed phase, but also a stress term modeling the Random-Uncorrelated Motion is needed. Simulations of a non-homogeneous particle laden turbulent gas flow allow to comp...
