Bubble characterization in horizontal air–water intermittent flow

•We studied air/water flow in transition from elongated bubble to slug regimes.•Ensemble-averaged image techniques were developed to detect liquid–gas interfaces.•Measurements of bubble nose and tail revealed their dependence on mixture velocity.•Radial movement of bubble nose toward pipe centerline...
