Droplet entrainment in vertical annular flow and its contribution to momentum transfer

Abstract

Abstract Simultaneous measurements were made of the size and the axial and radial velocity of drops entrained by the gas in annular flow. A model is developed to use these data to compute the rate of deposition or entrainment and the pressure gradient, ▽ρ E , due to drop interchange. ▽ρ E is a significant fraction of the measured total gradient, ▽ρ.
