Hydrodynamic analysis of core annular flow with a viscoplastic lubricant

•A two-fluid model to predict hydrodynamics of viscoplastically lubricated CAF.•The analysis is applied for suspension as well lubricated oil transport.•Viscoplastic lubrication with higher τy, lower k and lower n, lowers pumping power.•Lower n of the viscoplastic fluid decreases two-phase pressure...
