Mastering twoPhaseEulerFoam - One Fluidized bed - How to simulate a gas-solid fluidized bed using OpenFOAM (Hamidreza Norouzi & Ramin Khodabandehlou)
.png)
1. Brief Description of twoPhaseEulerFoam
twoPhaseEulerFoam is a solver for a system of 2 non-reacting compressible fluid phases. One phase in this system is always dispersed. So it is a good candidate for simulating bubble columns in gas/liquid systems or fluidized beds and spouted beds in gas/solid systems. The solver also solves the energy equation (enthalpy or internal energy) for both phases and couple them by the one-film resistance heat transfer model.
