Equation of state for hard-sphere fluids offering accurate virial coefficients.
The asymptotic expansion method is extended by using currently available accurate values for the first ten virial coefficients for hard sphere fluids. It is then used to yield an equation of state for hard sphere fluids, which accurately represents the currently accepted values for the first sixteen virial coefficients and compressibility factor data in both the stable and the metastable region...
متن کاملSimulation-based equation of state of the hard disk fluid and prediction of higher-order virial coefficients
We present new molecular dynamics results for the pressure of the pure hard disk fluid up to the hexatic transition (about reduced density 0.9). The data combined with the known virial coefficients (up to B10) are used to build an equation of state, to estimate higher-order virial coefficients, and also to obtain a better value of B10. Finite size effects are discussed in detail. The “van der W...
متن کاملAn 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 کاملDimensional interpolation of hard sphere virial coefficients
We examine the dependence on spatial dimension D of the Mayer cluster integrals that determine the virial coefficients B, for a fluid of rigid hyperspheres. The integrals vary smoothly with D, and can be characterized analytically in both the low-D and high-D limits. Dimensional interpolation (DI) allows one to evaluate individual Mayer cluster integrals at D = 2 and D = 3 to within about 1%. T...
