摘要：

A two-parameter viscosity model proposed previously for pure liquids is extended to correlate the kinematic viscosity-temperature behavior for liquid petroleum fractions. The coefficients in the viscosity equation are related to the characterization properties of the petroleum fractions and a generalized kinematic viscosity-temperature correlation is then developed, which needs only specific gravity at 15.6 degrees C and 50% boiling point as input parameters. The present method, when tested by predicting the experimental kinematic viscosities of 47 fractions from 15 world crude oils with total 250 data points, yielded reasonable results with an overall average absolute deviation of 4.2%.
