Transporting highly viscous materials (such as heavy oil) via pipelines is still a challenging task. The huge viscosity of such materials makes the transportation extremely energy-intensive. A promising solution to reduce the pressure drop (and thus energy) requirements is the water lubricated core-annular flow (CAF). In this work, we attempt to explore the interface dynamics of water-lubricated flow of Newtonian and non-Newtonian fluids as core-annular flow with a series of experiments.
