A new drag force model was developed to simulate gas-solid particle two-phase flows. The drag force model was based on the centrifugal correction, which can be presented by the gradients of the mixture velocities. For gas solid particle two-phase flow, the effects of the centrifugal force on the solid particles were realized by the correction of the gradients of the mixture velocities. According to the corrections, the terminal velocities of the dispersed phase (solid particles) were able to be calculated in multi dimensions. Through the comparisons of numerical simulations to the experiments and the other models on 2D and 3D cases, this model was validated. (C) 2016 Elsevier B.V. All rights reserved.
