An equation of state for accurate thermodynamic modeling of water and carbon dioxide from triple points to 647Â K and 100-200Â MPa

- An equation of state with near-critical corrections is developed for H2O and CO2.
- The vapor pressures of the two fluids are calculated within 0.033-0.078%.
- Saturated vapor and liquid volumes of the two fluids are also calculated accurately.
- Prediction of fugacity coefficients, residual enthalpies and entropies is excellent.
