Popis:	This paper deals with the numerical simulation of gas–solid two-phase flows in an Eulerian–Lagrangian scheme. The particle tracks are calculated using a recently developed exponential Lagrangian scheme and the approach presently used for the computation of fluid phase is based on a modified Lattice-BGK model. Different from earlier publications, the present study employs a two-way coupling mechanism to handle the interactions between carrier phase and dispersed phase in the model. This new model is applicable to simulating gas–solid two-phase flows. For example, based on the scheme, we have recaptured some phenomena of planar laminar particle-laden flow over a backward-facing step in this research and found a new interesting phenomenon.
