How to simulate a gas-solid fluidized bed using OpenFOAM®

In this tutorial you will learn how to simulate a gas-solid fluidized bed using OpenFOAM® (twoPhaseEulerFoam). The tutorial also contains a complete description of physical models  and available options through which you can customize your simulation. In addition, you can see the animation of this simulation here. The video is also uploaded on YouTube.

  • Description: The gas-solid fluidized bed is a flat bed with rectangular cross section with dimensions 150x28x2.5 cm3 . This bed is filled up to 40 cm with 275-microns spherical glass beads with the density of 2500 kg/m3 . The packing fraction (solid volume fraction) is assumed to be 0.6 and the maximum packing fraction was assumed to be 0.63. These particles are fluidized with air at ambient conditions (here we assume 1 atm and 283 K). This condition exactly corresponds to the experiments performed by Taghipour et al. [Taghipour, Ellis, & Wong, 2005. Chemical Engineering Science, 60, 6857–6867].
