To improve a void drift model used in a subchannel analysis, experimental data were obtained for air-water two-phase flows in a vertical channel made up of two subchannels. The data include the axial variations of void fraction, and flow rates of both phases in the respective subchannels. By fitting the above data, as well as our previous data, with Lahey et al.'s void settling model, we have determined a void diffusion coefficient in their model. It was found that the void diffusion coefficient for various slug, churn.and annular flows could be well correlated in terms of a newly developed turbulent Peclet number using a subchannel geometry factor.
