Abstract

A unified computational formulation for homogeneous mixture flows involving multiple phases and multiple species is presented. The formulation is based upon using a generalized equation of state that is valid for arbitrary fluids, including liquids, gases and supercritical fluids. Thermodynamic properties of the mixture are uniformly determined by using Amagat's law rather than Dalton's law for liquid-gas, liquid-liquid or gas-gas mixtures. Proper system conditioning for implementation of standard numerical procedures is obtained using appropriate scaling of the pseudo-time-stepping scheme. The capabilities of the approach are demonstrated using several applications involving multi-phase and multi-component mixture flows such as hydrodynamic cavitation, real gas nozzle flows, reacting flows and underwater propulsion.
