Some aspects of transport properties at high pressures (Modern aspects of physical chemistry at high pressure : the 50th commemorative volume)

Abstract

We present a review of transport properties i.e., self-diffusion, viscosity and thermal coductivity coefficients at high pressure. The pressure range of experimental results covered by this analysis will depend on the property or the effect which is studied. As the density is the relevant parameter, the density range includes moderately dense gases, dense gases, liquids, and solids. Particular attention is given to some regions of the phase diagram, as the liquid-solid transition or the critical region, where large variations of some of the transport properties are observed. Finally experimental data are compared with theoretical predictions based on Enskog's theory, modified Enskog's theory and computer simulations.
