Equations of State for Fluid Mixtures at High Pressures

A method that includes the use of modified equations of state has been developed to enable noniterative, efficient computation of the thermodynamic behaviors of gases and liquids at temperatures >100 K and pressures from 1 to 100 MPa. The method is intended to be particularly useful for calculating such quantities as partial molar volumes, enthalpies, entropies, compressibilities, and thermal expansivities of oxidant/fuel mixtures at given pressures, temperatures, and mass fractions in gas turbine and rocket engines.
