Summary
New absolute dynamic viscosity measurements of subcooled liquid oxygen are presented which were acquired in the pressure and temperature domains from 0.15 to 1.0 MPa and from 55.20 to 90.19 K, respectively. The measurements were acquired with an uncertainty of 1% at a 95% confidence level using a pressurized gravitational capillary viscometer specifically designed for subcooled liquefied gases. The measurements are summarized by Arrhenius-Eyring plot parameters, and interpreted with respect to the chemical reaction rate theory of viscosity by Eyring. The Arrhenius-Eyring plot parameters reproduce the dynamic viscosity measurements with only a 2% RMS error, which is remarkable considering just two parameters are involved, A, the factor which includes the weak pressure dependence of the dynamic viscosity, and E/R, the barrier energy of the flow, where R is the universal gas constant. Although the Arrhenius-Eyring plot parameters do not have a discernible pressure dependence in the present work, the pressure coefficient versus temperature for the dynamic viscosity was determined from line plots of the dynamic viscosity versus pressure. The pressure coefficients suggest that the pressure dependence is very weak, yet positive, and increases with decreasing temperature. Measurements at pressures an order-of-magnitude higher are required to confirm this suggestion. [Reprinted with permission from Elsevier. Copyright, 2007].
