Abstract

In this work, two CFD codes are utilized in Eulerian-Eulerian modeling of laboratory-scale cold model of CFB. The objective of the work is to compare the accuracy and performance between the utilized codes, which are the commercial code of Ansys Fluent 17.0 and open-source code of OpenFOAM 3.0.1 with the solver twoPhaseEulerFoam. The same mesh and as similar settings as possible are utilized in transient simulations. The average profiles of pressure, velocity and solids volume fraction are similar between the CFD codes and match well with the measurements from the cold model. The computational times and performance are compared and OpenFOAM was found to perform better, but having more limited time step size.
