An augmented hard core equation of state generalized in terms of Tc, Pc, and ω
A generalized Carnahan-Starling hard core equation of state perturbed by attractive forces is presented for nonpolar fluids. The information required is the critical temperature the critical pressure and Pitzer's acentric factor. Realistic predictions of the critical compressibility factor and second virial coefficients are ensured and the representation of pure compound liquid molar volumes in the reduced temperature range of 0.5 to 1.0 is improved significantly over cubic equations of state. The equation of state is then modified for 1-alkanols and extended to mixtures by augmenting the mixing rules of Arai et al.
