Experiments have been carried out on two-phase flow of air and aqueous polymer solutions (both inelastic and viscoelastic) in a 42 mm internal diameter pipe under isothermal conditions. Average liquid holdup and two-phase pressure drop have been measured for a wide range of combinations of input rates of air and polymer solutions. It is demonstrated that the average liquid holdups for inelastic liquids in both laminar and turbulent flow and for viscoelastic liquids in turbulent flow are in conformity with values obtained for shear-thinning suspensions. However, for viscoelastic liquids in laminar flow the elasticity gives rise to an increased holdup. Elasticity appears to have little effect on two-phase pressure drop. For laminar flow of liquid, minimum drag ratios are consistent with figures obtained for shear-thinning suspensions; and for turbulent flow, the Lockhart-Martinelli correlation is applicable.
