The development of a three-fluid model of two-phase flow for a dispersed-annular mode of flow in channels: Size of droplets

A three-fluid one-dimensional model of two-phase medium is suggested which is based on the equations of conservation of mass, momentum, and energy for the gas phase, dispersed phase (droplets), and film. The model includes the equation for the number density of particles of the dispersed phase, which is used to determine the average particle size. The calculation results are compared with the experimental data on the size of droplets in dispersed flow.
