High Pressure Viscosity of a Polyphenyl Ether measured with a New Couette Viscometer

Nature Physical Science volume 245, pages 15–16 (1973)Cite this article

Abstract

IN our study of the viscoelastic properties of lubricating fluids over wide ranges of temperature and pressure, the need arose for measurements of viscosity at low rates of shear and high pressures up to viscosities rather higher than had been measured hitherto. This required the design and construction of a new form of viscometer. But we realized that such measurements could be of more immediate application in the fields of elastohydrodynamic lubrication and hydraulics. Here we report such an application in a short investigation of a rather unexpected result published recently1, that the viscosity of a liquid approaches, and may even attain, a constant value as the pressure is raised.
