โœฆ Synopsis

An equation is proposed to calculate the viscosity and thermal conductivity coefficients of methane from the dilute gas to the dense liquid. The range of validity of the equation is approximately 95-400 K for pressures up to 50 MPa (~500 atm). The reliabilities of the coefficients calculated are estimated at approximately 2% and 5% for the viscosity and thermal conductivity coefficients, respectively. The equation includes a contribution for the thermal conductivity enhancement in the critical region.

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.

We discuss the estimation of viscosity and thermal conductivity coefficients of He 4 between 2 and 50 K for densities up to 0.2 g/cm 3. The literature is reviewed and data sources listed. It is very obvious that much more data than are available are required. Interim estimates of the coefficients ar
