An Improved Correlation for Second Virial Coefficients of Pure Fluids
In the present work, a modified correlation is presented for the second virial coefficients of both polar and nonpolar fluids based on the corresponding states principle. The second virial coefficients of gaseous polar and non-polar compounds were calculated and compared with experimental data and with other correlations. Comparisons with the existing correlations show that the present work is ...

متن کاملMODIFIED NUMERICAL TABLES FOR THE CALCULATION OF NON-SPHERICAL CONTRIBUTION TO SECOND VIRIAL COEFFICIENTS AND THE CORRELATION EQUATIONS OF STATE FOR CO,, CS, AND C6H6
A revised analysis of the effect of long-range nonspherical terms in the intermolecular potential on the second virial coefficient is presented with a preferred Hartree-Fock-Dispersion functional (HFD-C) spherical core treatment of the integrations for small intermolecular distances. A set of modified numerical tables for the accurate calculation of the nonspherical contribution to the sec...
متن کاملTemperature Dependence of the Second Dielectric Virial Coefficients of Rare Gases
Second dielectric virial coefficients BZ(T) of the rare gases Ne, Ar, Kr, and Xe are calculated in a broad range of temperature using accurate HFD-type interatomic interaction potentials and available information on the trace of the pair polarizability Aa. It is shown that the experimentally determined temperature-variation of BC(T) cannot be reproduced by existing theories. However, it is obse...
متن کاملSecond Virial Coefficients for Nonspherical Molecules and Their Experimental Measurements
The virial coefficients can be obtained from statistical mechanics in connection with the intermolecular potentials. The intermolecular potential of polyatomic molecules is usually assumed to consist of a spherically symmetric component plus a contribution due to asphericaity of the molecular charge distribution. In this study, the second virial coefficients have been calculated for N2...
