摘要：Combined with the state equation of chain-like fluids, a model for correlating and predicting viscosities of liquid mixtures under high pressures was established based on Eyring's absolute rate theory. Present model can be used to correlate satisfactorily the viscosity of liquid mixtures with only one adjustable and temperature independent parameter, and good agreements between the predicted values and experimental data for the selected systems are attained. For the 20 binary systems and one ternary system, 3075 data points from 0.1 MPa to 73 MPa, and from 273 K to 373 K, the overall average absolute correlated and predicted deviation are 1.47% and 2.62% respectively. Results calculated by this model are more accurate than those obtained by the friction theory (f-theory) for hydrocarbon mixtures.
