| Popis: | The aim of this modeling study is to improve the performance of the Peng-Robinson viscosity equation of state. To achieve this aim, the couple of Peng-Robinson viscosity equation of state and the proposed mixing rules has been applied for modeling the viscosities of the binary and ternary systems containing (nC5+nC8), (nC5+nC10), (nC8+nC10) and (nC5+nC8+nC10) for temperatures and pressures ranged (297.75-373.35) K and (49.95-246.26) bar, respectively. First, the pressure temperature-dependent and constant expressions for the binary interaction coefficients of binary systems have been determined. Subsequently, these empirical correlations of binary interaction coefficients have been applied to predict the viscosities for ternary mixture of (nC5+nC8+nC10 ). For this ternary mixture, the results of model show acceptable accuracy (overall AAD~7.77 % and 8.02 for mixing rule 1 and 2, respectively). |
