Free-volume viscosity model for fluids in the dense and gaseous states

cited By 78International audienceAn approach to model the viscosity of Newtonian fluids is presented. The approach is based on the free-volume concept and on the diffusion models of the molecules. It takes very correctly into account the transition between gas and liquid. The approach emphasizes the relation between microstructure, dynamic viscosity, and free volume in the understanding of such a complex property as dynamic viscosity
