Transport Properties of Fluid Oxygen

Supplementing the recently completed IUPAC tables for the thermodynamic properties of oxygen, this paper presents a data evaluation of the transport properties, viscosity, and thermal conductivity. From a comprehensive literature survey the available data have been complied, and their quality was assessed. Selected measurements were correlated to generate skeleton tables of the most reliable data along the vapor‐liquid coexistence curve and for the fluid region at pressures from 0.1 to 100 MPa and at temperatures from 70 to 1400 K. The set of correlations which was developed includes residual concept formulations as well as transport equations of state. These allow the direct calculation of viscosities and thermal conductivities from pressure and temperature as input variables. The simplified crossover model was employed to represent the enhancement of the thermal conductivity in the critical region.
