Two aspects in modeling two-phase turbulent flows by use of the stochastic Eulerian-Lagrangian method which were usually overlooked in the past studies are discussed and examined through two well-defined problems. It is evident that the inlet upi1 conditions have to be considered in the calculation to obtain correct solution of the dispersed-phase turbulence characteristics, in particular for the two-phase flows under the inlet conditions of kf < kp. It is also concluded that the transient drag coefficient has to be taken into account when the condition of the Stokes number large than O(101) is encountered in the investigated two-phase flow.
