A method of droplet behavior simulation in annular dispersed flow has been developed. Both droplet deposition and entrainment from liquid film are considered. Droplet entrainment from liquid film is calculated by an entrainment correlation and droplet behavior in turbulent flow is analyzed by Lagrangian simulation. The transition from annular flow with no entrainment to equilibrium annular dispersed flow was calculated for verification of this method. Analysis results can show the qualitative tendency of radial distribution of droplet mass flux, though entrainment rate must be adjusted for high liquid flow rate, in which gas turbulence is thought to be modified by high droplet density. In future work the effect of high droplet density on turbulence should be considered.
