Several empirical equations have been proposed of the interfacial friction factor in a gas-liquid tow-phase annular flow, but there exists a significant inconsistency among the results calculated by these correlations. In addition, none of them indicated good agreement with the present experimental values obtained in ripple flow regime. An experiment was made to collect the information on main parameters characterizing air-water interface, such as wave height, wave propagation velocity and wave frequency, possibly interrelated with the interfacial friction factor. Using the results, there of a new relationship between the interfacial friction factor and the parameters was introduced.
