Abstract

The pressure-volume-temperature (PVT) behavior of pure water is calculated with the associated perturbed anisotropic chain theory. The results are compared with existing experimental data. The pressure range of interest is from 25 to 250 000 bar and the temperature range is 473.15 to 1273.15 K. Special attention is paid to the near- and supercritical region. It is shown that, close to the critical point, the phase behavior of this compound cannot be predicted with a cubic equation of state within reasonable accuracy limits. The agreement between the experimental data and calculated results is very good for pressures up to 50 000 bar, including the near-critical region.
