Gas-liquid annular two-phase flow is an important flow pattern in terms of the film dryout at the high quality region in various kinds of heat exchangers. In the past, many investigations on an annular-dispersed flow in horizontal pipelines were conducted, and the behaviors of entrained droplets have been discussed. They, however, focussed only on spatially averaged values of various properties of the droplets. In the present experiment, an isokinetic sampling probe technique was used for the measurement of the droplet flow rate generated from an imitated disturbance wave constructed by injecting liquid through a slit mounted on the bottom of a horizontal duct. As a result, it is clarified that the correlation of the entrainment fraction proposed by Paleev-Filippovich is superior to that by others.
