Аннотация:Abstract Numerical simulation using computational fluid dynamics (CFD) technique associated with experimental verification is a useful tool for analysis of gas–solid multiphase flows. Simulations of the spouted bed fluid dynamic using two‐dimensional computational grids were accomplished in our previous works with good results. In this article, the patterns of solids and gas flows in a spouted bed were numerically simulated using the three‐dimensional (3D) Eulerian multiphase model. The minimum spouted condition was identified by the simulated solids volume fraction and pressure profiles. The simulated results show good agreement with experimental data and higher accuracy when compared with 2D simulations.
