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

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 com...
