Equation State for Fluid Mixtures Based on the Principle of Corresponding States with Two-Fluid Model (Application to Fluid Mixtures of Water+Ammonia System)

摘要

ew propose an equation of state for fluid mixtures of water+ammonia system which is ex- pressed in Helmhotz free energy as a function of temperature, molar volume and mole fraction. The IAPWS Formulation 1995 for water and equation of state by Tillner-Roth et al. For ammonia should Be used for each pure component with our equation. We applied the principle of corresponding states With two-fluid model to our equation for fluid mixtures. Accuracy of our equation was evaluated by Means of comparison with the experimental data for thermodynamic properties.
