Re-evaluation of experimental data on the second virial coefficient for steam and development of its analytical representation as a function of the internal energy
Original language description
The work presented in the paper is a part of broader effort to develop a formulation of the properties of dry and metastable steam suitable for CFD computations. 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. Also an analytical formula is presented to compute the second virial coefficientas function of internal energy in a range corresponding to the ideal-gas temperatures from 273.16 K to 1073.15 K.
