| 초록 | We propose a new model to describe the phase behaviors of the fluid mixtures based on the perturbation theory suggested by Song et al.. We modified the bonding term of the perturbed-hard-sphere chain (PHSC) equation byintroducing the form proposed by Chapman et al.. The proposed model predicts Monte Carlo simulation data forthe compressibility factor better than those of the PHSC equation in the entire density region.We also are able to describe the vapor-liquid equilibria (VLE) of pure fluids with three characteristic parameters.In the prediction of the specific volume of polymers, our proposed model shows better agreements with theexperimental data than those of the PHSC equation. By introducing two additional binary model parameters,we also predict liquid-liquid equilibria (LLE) of a binary fluid mixture including polymer solutions. |
