“…Hendl et al 7 reevaluated older data from their laboratory and derived adsorption-corrected values for B between 381 and 524 K. Their results, while internally consistent, for the most part disagree with the studies mentioned previously; we will discuss this disagreement in a subsequent section.…”

“…1 is the inconsistency of the data of Hendl et al 7 with the other data sources. Because the other three independent sources are in fairly good agreement, and because the B(T) function could not be made to agree with Hendl et al 7 without drastically worsening the prediction of °shown in Fig. 2, we disregarded these data.…”

“…Also, new data for B(T) have been published by several groups. [3][4][5][6][7] Our goal was to produce a correlation that took into account these new data and covered a larger temperature range. We limited our work to ordinary water (H 2 O).…”

A new correlation has been developed to represent the second virial coefficient of water (H 2 O) as a function of temperature. The formulation was fitted to experimental data, both for the second virial coefficient itself and for a quantity related to its first temperature derivative, at temperatures between approximately 310 and 1170 K. The high-temperature extrapolation behavior was guided by results calculated from a highquality intermolecular pair potential. The new correlation agrees well with the experimental data deemed to be reliable, and at high temperatures is a significant improvement over the best previous formulation.

“…The re-evaluation will be used for developing a new analytical representation of second virial coefficient as a function of the internal energy. As the earlier step a following function was developed Developed model is compared with the re-evaluated data, previously published virial coefficients by Adulagatov et al [16], Eubank et al [17], Hendl et al [18], Kell et al [19] and [20] and with previous models: IAPWS95 [4], Hill and MacMillan [21] and Le Fevre et al [22] as can be seen from figure 6 for lower internal energy of ideal gas and from figure 7 for higher one.…”

Abstract.A re-evaluation of the second virial coefficient of steam is presented in the paper. The work is a part of broader effort to develop a formulation of the properties of dry and metastable steam suitable for CFD computations. The re-evaluation follows up previous work by Harvey and Lemmon [1], however with a special care for the lower temperature region close to the triple point and including more experimental data. The second virial coefficient was evaluated from volumetric (pvT) data, calorimetric measurements for saturated vapor, steam expansion experiments (measurements of the Joule-Thomson coefficient and the isothermal throttling coefficient) and measurements of the speed of sound. To accurately evaluate the uncertainty of calorimetric measurements, the uncertainty of the temperature derivative of the saturation pressure was determined based on refitting of the IAPWS saturation pressure formula to the experimental data. In the second step, the evaluated data and their uncertainties were used to develop an analytical formula to compute the second virial coefficient as function of internal energy in a range corresponding to the ideal-gas temperatures from 273.16 K to 1073.15 K. The choice of internal energy and density as independent variables is required for the CFD computations to avoid time-consuming iterations.

“…As can be seen, there are far less experimental data available for the CO 2 -H 2 O-NaCl system than those for the CO 2 -H 2 O system. (Abdulagatov et al, 2002;Harvey and Lemmon, 2004;Hendl et al, 1997;Holste et al, 1987;Plyasunov and Shock, 2003;Tsonopouplos, 1974) to predict the thermophysical properties of CO 2 -H 2 O at low to medium pressures. The data generated using these correlations, however, deviate from experimental results rapidly with pressure.…”
