A hyperbolic model for inhomogeneous one-dimensional two-phase flow has been derived based on the macroscopic two-fluid formulation with separated conservation equations for the two phases. The features of the new model include the existence of real eigenvalues and a complete set of independent eigenvectors which can be expressed algebraically by the major dependent flow parameters. This allows numerical techniques to be applied which were originally developed for high speed single-phase gas flows and which make explicit use of the hyperbolic nature of the flow equations. Two different numerical schemes and results for selected test cases are presented.
