The process of destabilisation of an axi-symmetric, core-annular flow (CAF) of two Newtonian fully miscible liquids widely differing in viscosity is investigated. Formation of periodic structures is observed in experiments, predicted by the linear stability theory and simulated numerically using the volume of fluid method (VOF). Possible influence of this phenomenon on mixing on the molecular scale is discussed.
