Abstract: 
A turbulence gas-solid model that combines eulerian approach and lagrangian approach is formulated, which takes inter-particle interaction into consideration on the base of kinetic theory. The numerical algorithm is included. Comparison of the model results with the experimental results of Miller and Gidaspow (1992) showed good agreement.
