An algebraic-logarithmic model for two-phase stratified turbulent channel flow is presented. The various aspects of the model compare favorably with a wide range of data from the literature. The model is characterized by its ability to reproduce the effect of interfacial waves and momentum transfer, associated with large pressure drop increases in stratified flows. Its analytic nature allows for the derivation of relatively simple preintegrated (integrated analytically prior to run time) expressions for the mean wall and interfacial friction. The corresponding pipe flow expressions, ideally suited for 1-D computer models, are obtained by hydraulic similarity. The pipe flow friction formulae open up for the simulation of large pipeline systems with the consistency and accuracy of a cross sectional description, while maintaining the evaluation speed of a 1-D model. The work described in this article was motivated by the multiphase flow challenges met in the development of gas-condensate fields like Ormen Lange and Snøhvit on the Norwegian continental shelf.
