| Abstract: | A survey of existing models turbulence for particulate turbulence modulation in two-phase flows is carried out and an improved model for considering the effects of the dispersed phase on the turbulence of the carrier phase is suggested. The appropriate empirical constants in the turbulence model is determinated according to the available experimental data. An improvement of the numerical prediction of available experimental data is observed as compared with previous numerical results. |
