Cluster–associate model for the viscosity of oıl sludge (Atasu-Alashankou) mıddle fractıons

The scientific novelty of the work consists in displaying the temperature dependence of viscosity by a cluster-associated probabilistic mathematical model, the hierarchical structure of which is adequate to the physical nature of particle aggregation without taking into account their specific structure, but taking into account changes in the degree of their association with an increase in temperature. The calculation of the data was carried out on the basis of a new cluster-associative equation, which was derived within the framework of the concept of chaotic particles. The calculated data in the temperature range from the boiling point and the end of boiling are given. It is shown that the degree of cluster association naturally decreases with increasing temperature, equal on average to three-four-part cluster arrangement in the associate. The cluster-associative model is compared with the Frenkel equation in logarithmic coordinates.
