β¦ Synopsis
This paper discusses the experimental information on the transport properties of dense simple fluids with emphasis on the compressed and saturated liquid states. Similarities and differences in the wide range density and temperature dependencies of the viscosity and thermal conductivity coefficients are summarized. The excess transport properties of argon, helium, hydrogen, oxygen, and carbon dioxide are graphically compared in the same reduced density and temperature ranges.
Procedure
Data for most of the monatomic and simple polyatomic fluids have been examined but only the behaviour of argon, helium, hydrogen, and oxygen will be discussed in some detail. This choice is dictated by limitations in the range and reliability of the available data and by the thought that these fluids include examples of what is usually meant by a simple fluid. Table 1 gives the sources of viscosity, thermal conductivity, and compressibility data referred to in this analysis.

The self-diffusion coeffkient, shear viscosity and thermal conductivity of the Lennard-Jones fluid have been determined over essentially the whole phase diagram at densities below the solid-fluid coexistence line. This data is fitted to simple expressions developed from those proposed by Dymond.
Analytical solutions are given for the velocity and temperature profiles in non-Newtonian fluids between two infinite parallel planes, one of which is moving fast enough that viscous dissipation heating effects are important. The temperature-and shear-dependence of the non-Newtonian viscosity is tak
