J. Tribol 140(3), 034501 (Jan 16, 2018) (3 pages) Paper No: TRIB-17-1253; doi: 10.1115/1.4038579 History: Received June 23, 2017; Revised October 16, 2017

This paper describes the construction and testing of a simple, experimental tool setup that enables determination of the pressure–viscosity relationship for high viscosity oils. Comparing the determined pressure–viscosity relationship with a reference rheometer measuring the viscosity at ambient pressure yields reasonable agreement. The computed viscosity at elevated pressures was well represented by the Chu and Cameron model.
