... entrainment and deposition have relevant impact on annular flow properties, such as pressure drop and film thickness, as vastly shown in literature. Several authors have described physical mechanisms for droplet entrainment and deposition; many of those are related to disturbance waves. The objective...

... of the phases: droplets into the gas phases and gas bubbles into the liquids. In this paper we will study the entrainment of bubbles into stratified flow. Most previous work on this theme has concentrated on the overall entrained fraction, since existing instrumentation did not allow a more detailed...
