In the framework of the cluster associate model developed earlier by the authors, viscosity and fluidity are considered as the chaos sensitive properties of a liquid inherent in it not only in motion but also at rest, since they are based on the equilibrium Boltzmann distribution. In this model, the key characteristics are the thermal barriers of chaotization at the melting and boiling points, thereby the behavior of the liquid is determined by the action of three energy classes of particles—crystal-mobile, liquid-mobile and vapor-mobile. When turning to the consideration of viscosity and fluidity from simple substances to complex inorganic and alloys, more in-depth justification of the chaotization barriers responsible for the formation of clusters from the number of crystal-mobile particles is required, as well as methods for adapting the cluster associate model to experimental data.
