A Comparison of Ansys Fluent and MFiX in Performing CFD-DEM Simulations of a Spouted Bed

Abstract: The CFD-DEM methodology is a popular tool for the study of fluid–particle systems, and there are several programs that permit using it. In this study, we employed it to simulate a pseudo-2D spouted bed, comparing the performance of the programs Ansys Fluent and MFiX. The results are analysed and commented on in terms of both accuracy and computational efforts. Despite the similarity of the setup, MFiX seems to perform significantly better. The similarities and differences between the two programs are discussed… Show more

“…This implementation attempts to balance fluid flow resolution and computation speed. However, the grid size requirements can sometimes result in inaccuracies in predicting the fluid phase [16]. An example of this limitation applies to air seeding distribution systems, more specifically vertical seed distributor heads.…”
