A semi-empirical spectrum model is proposed todescribe the experimental data of the steady shear propertiesof a Shengli waxy crude oil near its gel point, where sophisticatedstructural effects become apparent due to the existenceof waxy crystals in the crude oil. The model, consisting of atime spectrum, can well fit the steady shear viscosities of thewaxy crude oil over the whole experimental shear rate regionfrom 10~-4 to 10~2 s~-1.Two other experiments on complex fluidsreported recently in the literature are also well describedby this model demonstrating the applicability and accuracyof the model.
