Abstract
A new approach towards the prediction of the interfacial friction factor in two-phase wavy film flow is presented. It is shown that the associated interfacial shear and pressure drop are directly related to the waviness characteristics and to the mobility of the interface. Comparison of the predicted interfacial shear factor with experiment for concurrent downwards annular flow is satisfactory. The proposed approach appears to offer a possibility for closed form modelling of the interfacial shear and wave characteristics.
