But, the q function model that is used for the EOS has many system-dependent parameters, which makes the equation of state less predicting. In this research, we derived a new crossover function model that has less numbers of parameters based on parametric sine model and developed the crossover equation of state. We used the Lattice Equation of State as a reference EOS. Our Crossover Equation of State has only one additional crossover parameter, compared with that previous crossover equation of state has three or four additional crossover parameters. We calculated thermodynamic properties of various pure fluids, phase equilibria of mixture systems and solubility of solid in supercritical solvent. And this EOS and this EOS represented these properties well. Extended Abstract Status: Not Uploaded | ||
