Abstract

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 the transformation of the system of governing equations into the characteristic form and the derivation of the compatibility relations for the different wave propagation processes. The advantages of the new model for the numerical simulation of two-phase flows is discussed in some detail.
